Dearest Archana,

Tell us more about these oddly-formed logical expressions:
Is case significant?
Is (transcription AND factor)NOT(control OR regulat) to be understood as (transcription AND factor)AND NOT(control OR regulat)
Will there be other operators besides AND, OR and NOT? (eg XOR, !, NAND)
How should NOT scope? eg, given (NOT blood AND soil) what do you want extracted?
Where will these odd expressions be coming from? User type-in?
What do you want done with unbalanced parens?
