As my library grows, I'm using the search more and more to find relevant content.

I would love a way to match exact words. Using double quotes matches exact words or phrases but will match substrings. When searching for acronyms or short words, I'm getting too many irrelevant results as a result. Example: searching for "ASTS" will yield hits on "lasts", "forecasts", "enthusiasts", "breakfasts", and a number of other irrelevant hits. A way to limit matches on words would greatly improve search results in numerous instances.
