Re: Payload Fields - Are they still best practise?

[Markus Jelsma]

Hello Ash,

We rely heavily on payloads to do the Part-of-Speech scoring for user
queries. When using edismax, you must translate all underlying Query
objects to their Payload supported counterparts, i believe that is in
the rewrite() method. Payloads are an excellent tool to distinguish
homonyms, to make a distinction between verbs, nouns and proper nouns
etc.

I don't have our code at hand, but there is some ancient code
available [1] that did just that. Just be aware that payloads have
changed a lot in the decade. Nothing what you see there will work
today.

Regards,
Markus
