Subject [jira] [Commented] (SOLR-7167) ANY operator synax - score only top matching term
Date Thu, 26 Feb 2015 16:36:04 GMT

    [ https://issues.apache.org/jira/browse/SOLR-7167?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14338662#comment-14338662

Alexey Kozhemiakin commented on SOLR-7167:
------------------------------------------

Mikhail, it's not about term frequency or performance, it's about relevancy and about avoid
over-boosting of documents if several synonyms matched the query.

>             Project: Solr
>          Issue Type: Improvement
>          Components: query parsers
>    Affects Versions: 5.0

> When we query
> (<term A> OR <term B> OR <term C> OR <term D>)
> and in case a document contains 2 or more of these terms: only the highest scoring term
should contribute to the final relevancy score; possibly lower scoring  terms should be discarded
from the scoring algorithm.
> Ideally I'd like an operator like ANY:
> (<term A> ANY <term B> ANY <term C> ANY <term D>)
> that has the purpose: return documents, sorted by the score of the highest scoring term.
