Parse a search string

[Mufasa]

Does anybody have any code that will take a search string and parse it in to
the appropriate parts?

For instance: +google -news -bush

TIA - J.

It's a very vague question. But, assuming you've got a string and you
want it split into parts where spaces (or any specific character) are the
separator: String.Split().

Not sure why you can'yt just split on space, then evaluate each to see what
the first character is and if its minus sign do one thing, else do something
if its a plus, or do something if its neither
