George -
There are a number of SQL Server specific ways you can do this. Email me
off-list as the solution is not relevant to Lucene.

RegexQuery?

Instead of just putting the keys in the index, can you put all the data you
might be getting out to display to the user, or whatever the final thing is?
That's what we do.Search on the id as you are, and then the hit has
documents that are loaded with all your final information instead of just
The standard way to do this is to additionally index the reverse of all
strings/tokens, potentially in a different field "reverse:", ie index
forward:abcd as well as reverse:dcba. Then in queries of the form
"*cd", reverse the query to "dc*" so that you end up with "reverse:dc*"

All,
I have created a Lucene index from data in a SQL Server db. When I conduct a
Lucene search, I get back in the hits the primary key (WorkID) and the
scores associated with the hits. Then using the list of WorkIDs, I query the
database for the other associated information of the assets associate

Hi Harini,
I updated QueryTermsExtractor in Subversion last night
to support your requirement.
The JUnit test is also updated with a field-specific
example.

For those interested in profiler info, look here:

Hi Chris,
Can we pass a different query object for searching and a different one
to the highlighter? I am not sure of that.
In any case, based on Mark's suggestion I modified the
QueryTermsExtractor class and filtered the query terms by the fieldName.
Attached is the modified file.
Thanks,
