Thesaurus Support In SQL Server Full Text Service

Hi,
 
I€™ve been trying to add keywords to the thesaurus used for SQL Server 2005 Full Text services but do not seems to get any improved results.
For example, I have a catalogue of article titles which contains titles such as €˜CRM€™ and then some others use the words €˜Customer Relationship Management€™, the ideal solution I would have thought was SQL Servers thesaurus support, I€™ve been though and added the values:
 
<expansion>
       _{customer relationship management}
       _crm
 </expansion>
 
to the txGlobal.xml file in the SQL Servers FTData directory, I then amended by test query to use this clause:
FORMSOF(THESAURUS,"CRM")
The idea being that when I search for CRM it will bring back articles with Customer Relationship Management also. However I€™m just getting results for the same results as for the word 'CRM' and no expansion is taking place it would seem.
 
Would anyone be able to clarify what the best approach to making this work would be:

Do I need to restart the SQL Server FullText service after making any changes to the XML files?
(Done this, no sucess)


Do I need to restart the SQL Server service after making any changes to the XML files?
(Done this, no sucess)

Do you need to re-populate the full text catalogues after making a change the XML files?
(Done this, no sucess)
 
If this syntax correct when trying to utilise the thesaurus?
CONTAINSTABLE (Article_Metadata, *, €˜FORMSOF(THESAURUS,"CRM")€™ )
(It doesn;t give any errors, just no improved results over:
CONTAINSTABLE (Article_Metadata, *, €˜"CRM"€™ )
 
 
Any help would be appreciated.
 
Thanks
