Performance Bottlenecks Due To Full Text Search Indexing.
Apr 19, 2000
I am about to heavily index a table and have to include atleast 3 to 4 olumns in the fulltext index for this table.
The table is updated very frequently and the also the columns that are involve in the fulltext indexing undergo frequent updates.
As of now, I can't avoid using full text indexing as these columns are very very lengthy and basically contail text.
The users of the database will give some key words as the search criteria
to get infomation as to what they are looking for.
How frequently should I update my full text catalog.
This is a scenario where the full text is operating on various tables and
each of thses table might be containingaround 300,000 to 800,00 rows.
I would appreciate an intelligent siggestion as I need it as soon as possible.
Thanks and have a wonderful time ahead.

Hello everybody,
I have installed SQLServer 2005 for take advantage of full text seach features.
When I start full population, there are some rows that cause error and not are indexed.
I see the log in C:ProgrammiMicrosoft SQL ServerMSSQL.1MSSQLLOGSQLFT0000700005.LOG. In this file there are seven rows that have error and for everyone a line that say:
"Error '0x8004fd01: The IFilter::Init() function call failed.' ... full-text key value 0x495532303045594154504B55. Attempt will be made to reindex it. The component 'pdffilt.dll' reported error while indexing. Component path 'C:ProgrammiFoxit SoftwareFoxit PDF IFilterpdffilt.dll'."
With different full-text key value for every line.
My question is:
1) Start from a full-text key (ie. 0x495532303045594154504B55), how I arrive to the record in the source table for understand which is the problem?Otherwise how can I examine the problem if I don't know the row that cause the error?
2) What is the error 0x8004fd01?
3) Could be that the PDF filter of Foxit is better than Adobe? With Adobe filter (version 6) my full pupulation is endless!
Thanks!

We have an iFilter to extract text on emails and their attached files. I have encountered 5 emails that receive the following error code, but I cannot find anything on the error code: Error '0x80fc7586' occurred during full-text index population for table or indexed view '[RIA_Unindexed].[dbo].[Emails]' (table or indexed view ID '485576768', database ID '31'), full-text key value 'E11264A2-A17D-E511-80E0-005056B240B1'. Attempt will be made to reindex it.After a number of retry attempts they will fail to index.what does error code  '0x80fc7586' refer to, I have not found it.
Since the first two bytes of the error code are the severity and facility reporting the error, I stripped off that information and looked for error 0x7586 or 30086. That error reported "Too Many products".Theses emails being indexed contain attachments with large attachments that then the attachment chunks are being called for from the fdhost may result in too many chunk segments, or more likely there are some repeating words in the extracts like 4 million occurrences so right now I am testing that condition. To see if the word breaker is throwing the error.

Hi
I have a Full Text index on a table with an image field that is successfully indexing .doc, .pdf and .rtf files.
Keyword searching this is no problem.
What i want to be able to do is perform a similarity search. by this i mean pass in a Key_ID (documentID) and have the database return a list of Key_IDs (documents) which are similar.
By similar i mean contain mostly the same keywords in roughly the same quantities
Thanks

Hi, I was wondering if any SQL Server gurus out there could help me...I
have a table which contains text resources for my application. The text
resources are multi-lingual so I've read that if I add a html language
indicator meta tag e.g.<META NAME="MS.LOCALE" CONTENT="ES">and
store the text in a varbinary column with a supporting Document Type
column containing ".html" of varchar(5) then the full text index
service should be intelligent about the language word breakers it
applies when indexing the text. (I hope this is correct technique for
best multi-lingual support in a single table?)However, when I come to query this data the results always return 0 rows (no errors are encountered). e.g.DECLARE @SearchWord nvarchar(256)SET @SearchWord = 'search' -- Yes, this word is definitely present in my resources.SELECT * FROM Resource WHERE CONTAINS(Document, @SearchWord)I'm a little puzzled as Full Text search is working fine on another table that employs an nvarchar column (just plain text, no html).Does the filter used for full text indexing of html expect certain tags to be present as standard? E.g. <html> and <body> tags? At present the data I have stored might look like this (no html or body wrapping tags):Example record 1 data: <META NAME="MS.LOCALE" CONTENT="EN">Search for keywords:Example record 2 data: <META NAME="MS.LOCALE" CONTENT="EN">Sorry no results were found for your search.etc.Any pointers / suggestions would be greatly appreciated. Cheers,Gavin.UPDATE: I have tried wrapping the text in more usual html tags and re-built the full text index but I still never get any rows returned for my query results. Example of content wrapping tried - <HTML><HEAD><META NAME="MS.LOCALE" CONTENT="EN"></HEAD><BODY>Test text.</BODY></HTML>I've also tried stripping all html tags from the content and set the Document Type column = .txt but I still get no rows returned?!?

I have a table with 3M rows that contains a varchar(2000) field withvarious keywords. Here is the table structure:PKColumnImageIDFullTextColumnThere is an association table:ImageIDContractIDNow, I want to do a query where the ContractID = x and Contains someword in the FullTextColumn. There is an association table that mapsImages to Contracts - so I can't use the trick of putting the Contractcode in the FullTextColumn.I'm finding that first the FTS service is performing a search on theKeyword (which can take a long time if 100K rows are returned) thenjoining to the association table for the particular contract.Is there anyway to make this faster by telling the FTS service, onlysearch this subset of rows for the keyword based on the contract.Sorry if this sounds convoluted. Appreciate any help you can suggest.Thanks!

I am using the following plumbing code to search a database column for a keyword. I can't use full-test indexing so I came up w/ this work around. But It has many flaws so I'm looking for a better way. Thx in advance.
'Open sql connection
SqlConnection1.Open()
Dim datareader2 As SqlClient.SqlDataReader
datareader2 = cmdFindRowsWithKeyword.ExecuteReader
Dim strMsg As String
Dim intRowToFlag As Integer
Dim strRowsToGet As String
Dim strKeywordAsTyped As String
Dim strKeywordAllCaps As String
Dim strKeywordAllLower As String
Dim strKeywordFirstLetterCap As String
Dim FirstLetter As String
While datareader2.Read
intRowToFlag = datareader2(0).ToString
strMsg = datareader2(1).ToString
'Assign keyword as typed to variable
strKeywordAsTyped = txtSearchFor.Text
'Assign keyword as typed to variable then convert it to all uppercase
strKeywordAllCaps = txtSearchFor.Text
strKeywordAllCaps = strKeywordAllCaps.ToUpper
'Assign keyword as typed to variable then convert it to all lowercase
strKeywordAllLower = txtSearchFor.Text
strKeywordAllLower = strKeywordAllLower.ToLower
'Assign keyword as typed to variable then convert it so just the first letter is in uppercase
strKeywordFirstLetterCap = txtSearchFor.Text
FirstLetter = strKeywordFirstLetterCap.Chars(0)
FirstLetter = FirstLetter.ToUpper
strKeywordFirstLetterCap = strKeywordFirstLetterCap.Remove(0, 1)
strKeywordFirstLetterCap = strKeywordFirstLetterCap.Insert(0, FirstLetter)
'If the string contains the keyword as typed in all caps all lowercase or w/ the 1st letter in caps then flag that row.
If strMsg.IndexOf(strKeywordAsTyped) <> -1 Or strMsg.IndexOf(strKeywordAllCaps) <> -1 Or strMsg.IndexOf(strKeywordAllLower) <> -1 Or strMsg.IndexOf(strKeywordFirstLetterCap) <> -1 Then
cmdFlagRowsWithKeyword.Parameters("@recid").Value = intRowToFlag
SqlConnection2.Open()
Dim datareader3 As SqlClient.SqlDataReader
datareader3 = cmdFlagRowsWithKeyword.ExecuteReader
datareader3.Close()
SqlConnection2.Close()

full text indexing
Hi,
In SQL Server 2005, if I set full text indexing enables in column MyDesc and
1. use “Select * from MyTable where MyDesc LIKE ‘%abc%’� would this be using full text indexing? Or have to use Contains to get it be in use?
2. Once I create the full-text index, should I be setting it to populate periodically? Isn’t it populating itself?

Recently the full text catalogs no longer work on my sql server. We have tried a lot of different things to get them working and all have failed. I am totally at a loss. The service is running under the local admin and the local admins have sysadmin permissions. We have removed the catalogs and re-added them. We have removed the catalogs changed the DB to disable full text indexing. Checked the registry for the left over entries. Run sp_fulltext_service 'clean_up'. We have tried many difference combinations and tried restoring from backup. Nothing works. If anyone has ANY ideas I would greatly appreciate the help. We are running SQL 7.0 with SP3.

I have a table of product inventory I want to be able to search using the CONTAINS and/or FREETEXT functions. There are actually 4 columns I want to be searchable: brand, product name, etc. Since the table can have only one full-text index, should I just define an index on all 4 columns? It would be large in relation to the table, but the table itself is small (~600 rows). The index would not exceed the 900 byte limit.
Will this give me problems in terms of workability or performance? Is there a better approach? I could also just use LIKE searching, but it's significantly less sophisticated.
Thanks in advance.

Hi,
I am working on programming a knowledge base using ASP and MS SQL and we're running into the problem of how to search it... In that past we've just had a type of like statement... but this isn't really a search function and isn't really doing the trick...
So, what I'm thinking is that we might be able to use the full-text indexing service on Microsoft SQL server and then somehow search the full-text index from an ASP page and then procede with the db interface from there.
Are there better ways of searching MS SQL databases which I'm not aware of? Is it possible to access the full-text index from an ASP page and how would you do this? Are there documents that people could recommend on how to setup full-text indexing on MS SQL Server?
Thank you in advance, ( )

Hello everyone,
My questions are about installation (setup) and perfromances.
I have seen that, by default, all database user's files are set to : Use full-text indexing.
If we don't use full-text search at all, would it be a good idea to turn it off?
It seem impossible to turn it off at database creation using the T-SQL : CREATE DATABASE statement. Is it?
Having this parameter set to ON by default must incur an overhead. Rigth?
Best regards.
Carl

Trying to make a full-text table of a few tables in SQL server 2000 using the SQL Server Managment Studio. I am getting the following error when I then try to view the columns using the table. The column it is having a problem with is just a varchar text column. I have tried a few different tables and each time it has a problem with one of the columns. It does not give me an error when creating the full-text table. Anyone have any information on this?
I check on a full text table I made a while ago and it is giving me the same error but searches on it seem to be working, but cannot tell if it is using the one column it is having an issue with.
Property TypeColumnName is not available for FullTextIndexColumn '[MyColumnName]'. This property may not exist for this object, or may not be retrievable due to insufficient access rights. (Microsoft.SqlServer.Smo)

Hey guys,
I'm about to deploy full-text searching to complement
ASP.NET/C#.NET. I unfortunately have not had much experience in
Full-Text Indexing...
I will be creating catalogs for each table in the database (end-users
pretty much require that we are able to search by
anything). I see that there is a catalog population
schedule...typically, what is the best practice for updating the
catalogs? The database entries will most likely be updated
frequently, as it contains the end-users curriculum vitae. Would
once a day, say midnight, be a sufficient schedule?
And also, as it pertains to best practices, is the method I am applying
the best way to do this (a catalog per table)...I have about 30 tables
in a relational model...is there a better way to catalog the entire
thing instead of table by table?
Thanks a lot for the help!
Eric...

I was trying Full text indexing on my database. it seems to work fine on all databases except one. On one particular database it returns '0 results' immediately even though the table has a large number of records.
The search returns just fine if tried on the same table on a different database on a different server.
Does anyone have a faintest clue as to what could be wrong ?
please reply ASAP.
Thanks

I am having a few tables in my database on which I am implementing
FullText Searching.
As the tables are huge, full population of the catalog takes a lot of time.
I want to go for incremental population but I did not have a timestamp column
for this purpose when I initially designed the database.
Is there any way to ensure incremental population without the timestamp column? Because of the design constraints I do not like to have a timestamp column and would like to avoid it if it is possible.
But with out that SQL performs a full population and it is taking more than two hours now for full population and I also have several databases on which I have to do the same but the structure is more or less the same.
What are the performance issues when users are accessing the database when full text catalog population is in progress?Does it slow down reads and writes?It is a web based application for the internet catalog for industrial suppliers and needs to be online with no performance degradation.
Any help and info on this is greatly appreciated.
Thanks

Hi,
I am using full text indexing to index an image column where I am storing HTML documents. Currently I have an extra column in my table storing the file extension (htm) so the indexer knows which filter to use for every row.
HTML is the only format I'll be indexing, so is there a way for me to set this somewhere else so I don't have to have a column full of htm values - this seems really wasteful, those htm's add up when there are millions of rows...
Thanks!
