[ARC5] Question about finding our treasures on eBay...

[J. Forster]

Why?

My 2nd string is intended to return all capacitors, except ceramic.

capacitor -ceramic  is supposed to mean "capacitor AND NOT ceramic"

It gets interpreted as something like "capacitors OR ceramic".

The way the eBay strings should be parsed is:

Word1 Word2    =  Word1 AND Word2
Word1 -Word2   =  Word1 AND NOT Word2
(Word1,Word2)  =  Word1 OR Word2
