Simple search argument verification

MJ. Smith

One difficulty in learning the search is that one can get zero results from an ill-formed search argument rather than an error message. I suggest the ability to partially verify a search argument by a function that (1) pairs up parenthesis, quote marks etc. either by color coding match pairs or by arcs connecting them (the latter is preferred) and (2) bolds all text taken to be Operators rather than search terms.
