I found a tipping point where the search being built changes with the number of qf fields being passed in.
Example search: "foo bar" solr 7.2.1 select?q.op=AND&defType=edismax&q=foo bar Debugging the query you can see it results in: "parsedquery_toString":"+(+(text:foo) +(text:bar))" Adding more qf values you get: "text name_text" "parsedquery_toString":"+(+(name_text:foo | text:foo) +(name_text:bar | text:bar))" "text name_text city_text" "parsedquery_toString":"+(+(city_text:foo | name_text:foo | text:foo) +(city_text:bar | name_text:bar | text:bar))" The search continues to build this way until I get to a certain amount of qf values. Large number of qf values: "34 values.." "parsedquery_toString":"+(+((+comments_text:foo +comments_text:bar) | (+zip_text:foo +zip_text:bar) | (+city_text:foo +city_text:bar) | (+street_address_text:foo +street_address_text:bar) | (+street_address_two_text:foo +street_address_two_text:bar) | (+state_text:foo +state_text:bar)..." Now the search is requiring both foo and bar to be in each qf field in the search, not foo to be in any qf field and bar to be in any qf field. I had to cut the number of qf values down to 15 to get it back to the correct search. Why is the search changing? Is there any way around this or a better way we should be doing the search? I realize we could copy all of the fields to the default text field. However, most of the fields are searchable individually as well as keyword searchable so specifying the fields vs using the default text field makes sense in that respect. Thank you, Aaron
