Anyone who can shed any ideas as what might be the best possible solution will be great
Hi, i'm trying to do a full text search on my site to add a weighting score to my results. I have the following database structure: Documents: - DocumentID (int, PK) - Title (varchar) - Content (text) - CategoryID (int, FK) Categories: - CategoryID (int, PK) - CategoryName (varchar) I need to create a full text index which searches the Title, Content and CategoryName fields. I figured since i needed to search the CategoryName field i would create an indexed view. I tried to execute the following query: CREATE VIEW vw_DocumentsWITH SCHEMABINDING ASSELECT dbo.Documents.DocumentID, dbo.Documents.Title, dbo.Documents.[Content], dbo.Documents.CategoryID, dbo.Categories.CategoryNameFROM dbo.Categories INNER JOIN dbo.Documents ON dbo.Categories.CategoryID = dbo.Documents.CategoryID GOCREATE UNIQUE CLUSTERED INDEX vw_DocumentsIndexON vw_Documents(DocumentID) But this gave me the error: Cannot create index on view 'dbname.dbo.vw_Documents'. It contains text, ntext, image or xml columns. I tried converting the Content to a varchar(max) within my view but it still didn't like. Appreciate if someone can tell me how this can be done as surely what i'm trying to do is not ground breaking.
Hello everyone ! I want to perform Full Text Search with SQL Server 2000. My documents (.doc, .xls, .txt, .pdf) are stored in a SQL Server field which is binary (the type of the column is image). I would like to know, how you can extract pieces of text from the documents. Example: I have a ASPX page with codebehind in C# making the search in a table in SQL server that is full text indexed. I make a search looking for the word "peace", than SQL server will take care about the search and return it to me the rows that match with that. But also I'd like to extract the 50 characters before and after where sql server found the word "peace" to show in the result page. Does anyone has any idea how to work around it ? Best regards. Yannick
I have a column in a table that has a type TEXT,when I pull the length of a row it returns 88222 but when I select from that column it dows not show all the text in the result set.
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
'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()
Can you not add a text column to a full text index?? If I change it to a nvarchar it works fine but if I change it to a text column it wont index. Anyone know how to fix this?
i am tring to create the full text catalog I am following the direction at http://technet.microsoft.com/en-us/library/ms189520.aspx but on the last command it gives me an error
'PK_problem' is not a valid index to enforce a full-text search key. A full-text search key must be a unique, non-nullable, single-column index which is not offline, is not defined on a non-deterministic or imprecise nonpersisted computed column, and has maximum size of 900 bytes. Choose another index for the full-text key.
also I tried the wizard in the managment express but it does not have a option when I right click on the table for Full-Text Index
I created a new catalog and a new index but when I start a search the grid come back empty I didnt insert any data into the table until after I created the catalog and index I dont think it has indexed the data yet. How do I force this or make it???? I have another example where I inserted data and then created the catalog and index and did a search and the proper rows came back but then I inserted new data and searched on a keyword that should have brought it up but nothing showed?
Hi, I have a SQL statement that works great when I don't use a SQL Parameter, but when I do it just takes the @Searchfor as literal text "@SearchFor" instead of the string @SearchFor represents. Any ideas? Below is the two versions of the sql statements sqlComm.Parameters.Add(new SqlParameter("@SearchFor", strSearchFor)); sqlComm.CommandText = "SELECT RANK, intID, chTitle, chDescription " "FROM FREETEXTTABLE( tblItems, *, 'ISABOUT("+ strSearchFor +" WEIGHT(1.0))') a " + "JOIN tblItems b on a.[KEY] = b.intID ORDER BY RANK DESC; ";
sqlComm.Parameters.Add(new SqlParameter("@SearchFor", strSearchFor)); sqlComm.CommandText = "SELECT RANK, intID, chTitle, chDescription " + "FROM FREETEXTTABLE( tblItems, *, 'ISABOUT(@SearchFor WEIGHT(1.0))') a " + "JOIN tblItems b on a.[KEY] = b.intID ORDER BY RANK DESC; ";
I have a Full-text search that is being performed on a variable (@Description) see part of querie below: WHERE (CONTAINS([Description], @Description) This search only seems to work when a text fo 3 or greater characters is used Ball, but not for "an" or "a". it also does not search on part of a word i.e. "Gard" of "Garden" Two things: 1) How do I perform the CONTAINS search for part of a word or "a". 2) How do I perform a search that returns all values, when I leave the input feild blank it returns no records. Many thanks in advance

I have implemented Full text search in my web application. I am using sql server 2005 database. I used “contains “Keyword for full text search. These are syntax as given below: CONTAINS ( { column | * } , '< contains_search_condition >' ) < contains_search_condition > ::= { < simple_term > | < prefix_term > | < generation_term > | < proximity_term > | < weighted_term > } | { ( < contains_search_condition > ) { AND | AND NOT | OR } < contains_search_condition > [ ...n ] } My search gives correct results according to AND NOT and OR. But, it is not working if I used AND. Please give me solution. Its very urgent for me……
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.
After following all of the steps in Swynk's Guide to Full Text Search, I still can't seem to retrieve any records from the full-text search. I get messages saying that I created the Index correctly and that I successfully populated the catalog. But when I View the Properties of the catalog, the Unique Word Count = 1 (but there are thousands of words in the table). I know that there is a record with the word "help" in one of the full-text indexed columns, but when I call Contains(column-name, 'help'), I recieve an empty recordset.
Does anyone have any suggestion on what I can try next?
