Well, if you consider that SQL backend is kept in mind, which may use this
information to translate search filters to SQL...
Currently I avoid messing with syntax and matching rules by converting filter to
most relaxed corresponding SQL (that is, CIS matching) to get "candidates", then
testing them against full filter with test_filter()...
