--------------------------------------

I implemented this feature once for a Solr-based query parser. It can be tricky since you don't won't to preclude the use of a trailing single-character wildcard. You can read about the rules/heuristics I used here:

> For many search applications, queries ending in a question mark such as {{foo bar?}} would *not* mean a search for a four-letter word starting with {{bar}}. Neither will it mean a literal search for a question mark.
> The query parsers should have an option to discard trailing question mark before passing to analysis.
