Subject Re: Give boost only if entire value is present in Query

Sorry Rick,
I didn't get it.
How will you give boost on other field when querying on some other field.
Or if you query on copy keyword tokenized field then it only matched when
entire query is matched.

Aman,
Use a copyfield so you can have a second field that uses a different
analysis chain. In the new field you just created for the copyfield, use
the lowercase type, or create a type using KeywordTokenizer in the analysis
chain. Then match on the original field, and boost based on the new field.
Cheers
Rick
