I'm not sure I would consider this a CLI "issue".  It may not be
intuitive, but it is an intentional part of the Xapian query parser's
grammar.  If a boolean prefix is followed immediately by a quote, then
the term is between that quote and the next quote, modulo an escaping
rule that lets you include a literal quote in the term by doubling it in
the query string.  Together, these rules let you reliably put anything
in a boolean search term.
