This is no good because it doesn't check for single or double quotes.
Inputting anything with quotes gives ugly ugly errors. Plus, Boolean
interpreters should group quoted words as a single term. It doesn't
check for malicious code input at all. I tried editing it to make it
better, but after lots and lots of work, I didn't get very far. If you
can fix it up, let me know =)

I was wondering if anyone knew of any good Boolean interpreters (NOT,

wouldn't put them into production. Frankly, I don't have the time,
patience, or ability to write a good one from scratch. Here are the
three I've found in case anyone's interested:

Thanks for that link... that's a great piece of code!
With error reporting cranked right up it throws a few warnings,
but no errors. It certainly performs as described.
The only thing it doesn't seem to do is check for +.
But adding that is a 30 second task.
If this isn't good enough for you, just what are you looking for?
