Thread:Project:Support desk/How to form a search query in MediaWiki with multiple terms in the srsearch parameter?

I have two terms A and B (strings) and I want all Wikipedia pages that have both these terms A and B, with no constraint regarding the order in which they appear and any phrase query or anything like that. I just want all result pages to be containing both these terms.

What is the syntax of the MediaWiki query that I should be constructing for the srsearch parameter?

Should I use srsearch="A|B" or srsearch="A&B" or srsearch="A,B" or srsearch=A|B

From the results I am getting, I am unable to make this decision.

Any advise is highly appreciated.
