Solr Payloads retrieval

[Fabiano Nunes <fa...@nunes.me>]

Hi!

I'm studying a migration from "pure" Lucene to Solr, but I need a crucial
feature:
Is it posible to retrieve payloads from Solr?

I'm storing the coordinates from each term in its payload to highlight
images in client-side.

Thank you,

Yes, check out the field type "payloads" in the schema.xml file. If you
set up one or more of your fields as type payloads (you would use the
DelimitedPayloadTokenFilterFactory during indexing in your analyzer
chain), you can then use the PayloadTermQuery to query it with, scoring
can be done with a custom PayloadSimilarity implementation. Check out
this (slightly dated) article for more information.
