Multiterms query and payloads
Hi to everyone,
I started to use payloads in my indexes.
However, I didn't find a class that permits to perform queries using
more than one term.
The only way that works is to use the BoostingTermQuery class, but by
using this class, I can search only one term a time.
Does exist a way to do a multiterms search or I have to implement a
workaround that aggregates the results of single term searches?
Any other suggestions are accepted.
Thanks to everyone.

Thanks for the advice...
I watch in the documentation, but I saw that the PayloadTermQuery
accept only one term a time... however, samething might be done with
the PayloadNearQuery.

In 2.9, there is now the PayloadNearQuery, which might help you.
Otherwise, the PayloadTermQuery is still a Query and can be used in a
BooleanQuery. Beyond that, you may need to write what you need, since
it doesn't exist yet.
