In Solr, can I apply a boost to each term in a phrase?

Usi开发者_如何学运维ng Solr, if I have a phrase:

"The quick brown fox jumped over the lazy dog."

Can I apply my own weighting to these words at index-time?

Something like this:

"The^1 quick^2 brown^2 fox^3 ..." etc

And, then, I'd like to have those numbers influence the score.

Thanks!

You might wanna check payloads: Lucid or ultramagnus. You can add weights to terms at index time this way.

You can use boost query. So if you are searching on title field, you can query saying bq=(title:The)^1&bq=(title:quick)^2&bq=(title:brown)^2 and so on...

You should be able to do so the way you have written it:

http://lucene.apache.org/java/2_4_0/queryparsersyntax.html#Boosting a Term

Boosting a Term Lucene provides the relevance level of matching documents based on the terms found. To boost a term use the caret, "^", symbol with a boost factor (a number) at the end of the term you are searching. The higher the boost factor, the more relevant the term will be.

"jakarta apache"^4 "Apache Lucene" By default, the boost factor is 1. Although the boost factor must be positive, it can be less than 1 (e.g. 0.2)
