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.

(Answering an old question in case anyone comes looking for an answer.)

If you type the search "A B" or "B A" into the search field, you'll get the same results. So, use URI-encoding ("+" for " ") and you'll have what you want: https://www.mediawiki.org/w/api.php?action=query&list=search&srsearch=B+A&srbackend=LuceneSearch&format=jsonfm

Note that in doing this I got a strange error: bug 62608
