Title: Improvements & fixes to search_parser

* Extracted regular expressions to avoid redundancies
* Allowed unquoted 1-character categories (quoted ones worked, but it would not correctly round-trip and unquoted parsing wouldn't work at all)
* Improved parsing of freetext before/around categories
