[PATCH 4/6] lib: drop trailing slash for path and folder searches (infix)

Subject: [PATCH 4/6] lib: drop trailing slash for path and folder searches (infix)

Date: Fri, 21 Jan 2022 19:38:51 -0400

This resolves an old bug reported by David Edmondson in 2014. The fix
is only needed for the "boolean" case, as probabilistic / phrase
searching already ignores punctuation.

This fix is only for the infix (xapian provided) query parser.
