Hi Sowmya, "bq" is a great way of boosting, but you have to be using the Dismax Query Parser or the Extended Dismax (edismax) query parser, it doesn't work with the Lucene Query Parser. If you can use any of those, then that's the solution. If you need to use the Lucene Query Parser, for a user query like:
scientific temper you could create a query like: (scientific temper) OR (scientific temper AND (field1:[10 TO 2030]))^X being "X" the boost you want for those documents. with your query: scientific temper field1:[10 TO 2030] you are either adding the condition of the range value for the field (if your default operator is AND) or adding another way of matching the query (if your default operator ir OR, you can have documents in your result set that only matched the range query, and this is not what the user wanted). Hope this helps, Tomás On Wed, Jul 20, 2011 at 5:15 AM, Sowmya V.B. <vbsow...@gmail.com> wrote: > Can anyone throw some light on this issue? > > My problem is to: give a query time boost to certain documents, which have > a > field, say field1, in the range that the user chooses during query time.
