Extend Parse picker for 'Words in Texts' Search

[edstratford]

Currently, the parse properties option in 'Words in texts' only allows for choosing adjective, noun, verb, etc. -- but cannot use the parse options further down, (for example, genitive, singular noun). Allow user to further specify. Choices need not be complete. I.e., the user can choose 'genitive' for the Case, but not choose 'Number' and the search will not filter by number.

If possible, allow user to select more than one of the options that would normally only allow one selection whan applying parse properties. (For example, under Verb/Finite Verb/Tense -- user can select 'Preterite' and 'Perfect' and results will find these with results of an OR statement.)
