> 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="|"/>
