Hi All
I want my lucene to index documents and making some terms to have more
boost value.
so, if I index the document "The quick fox jumps over the lazy dog"
and I want the term fox and dog to have greater boost value.
How can I do that

Thanks a lot

How about using BoostingTermQuery and Payload?

1. In your Analyzer, put a value (boost value, for example) into payload of Token "fox" and "dog". 2. Define your Similarity and override scorePayload() method to boost marked token. 3. Use your Similarity when construct IndexSearcher, and use BoostingTermQuery when searching.
