Is there a need to use the common short conjunctions in your search terms?
Example:
search red widget or is should it be left out: search for red widget
another:
find yellow widget or find a yellow widget

It never hurts to put both. Actually, it is better to put both. If the short conjuction version never sees traffic, you aren't hurt. But if it does, than it helps to keep your CTR a tad higher as it draws a bit of the impressions off the non-conjuction phrase.
