Extend base input parser about garamond.jl

These should also work across multiple input parsers. For example, I might want to search for "coupon" with the base text parser, AND'd with a search for results within a given geographic area (using a latitude+longitude+radius parser), to determine which local businesses have coupons available in my city.

Indeed. The base input parser shoul dbe viewd as a "last-stage parser" that parses the query into a query data structure that is sent to the search methods. I'm envisioning a stacked parser approach here where parsers call the base one as one can build easily complex selection from the db.
So a flow would be "natural query --> (NLP parser) --> select-like query --> (Base input parser)"
