[jira] [Commented] (SOLR-12238) Synonym Query Style Boost By
Payload
[ https://issues.apache.org/jira/browse/SOLR-12238?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16443459#comment-16443459 ]
Alessandro Benedetti commented on SOLR-12238:
---------------------------------------------
[~softwaredoug] , [~dsmiley] and [~ehatcher] , when you have time it would be much appreciated if you let me know your view on this.
An initial patch with tests is attached.
Target of the functionality is to give users the ability to easy affect the synonym boost manually configuring the synonym.txt.
Being the patch at an initial stage I am happy to improve it and of course, feel free to motivate if you think it is not useful or handy for final users !

> Key: SOLR-12238
> URL: https://issues.apache.org/jira/browse/SOLR-12238
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Components: query parsers
> Reporter: Alessandro Benedetti
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> This improvement is built on top of the Synonym Query Style feature and brings the possibility of boosting synonym queries using the payload associated.
> It introduces two new modalities for the Synonym Query Style :
> PICK_BEST_BOOST_BY_PAYLOAD -> build a Disjunction query with the clauses boosted by payload
> AS_DISTINCT_TERMS_BOOST_BY_PAYLOAD -> build a Boolean query with the clauses boosted by payload
> This new synonym query styles will assume payloads are available so they must be used in conjunction with a token filter able to produce payloads.
> An synonym.txt example could be :
> # Synonyms used by Payload Boost
> tiger => tiger|1.0, Big_Cat|0.8, Shere_Khan|0.9
> leopard => leopard, Big_Cat|0.8, Bagheera|0.9
> lion => lion|1.0, panthera leo|0.99, Simba|0.8
> snow_leopard => panthera uncia|0.99, snow leopard|1.0
> A simple token filter to populate the payloads from such synonym.txt is :
> <filter class="solr.DelimitedPayloadTokenFilterFactory" encoder="float" delimiter="|"/>
