Subject Re: edismax, pf2 and use of both AND and OR parameter
Date Fri, 25 Aug 2017 07:21:01 GMT
Hi,

I am in the middle of the similar use case as provided , we have three
different fields on UI for searchany, searchall and searchexcept
respectively for OR,AND and NOT query , I need to know how do I make them
work along with Edismax.
We can expect any/all of the fields to have free text.
Any suggestions/guidance is truly appreciated.

Thanks,
Atita
