Search configuration?

[scoyote]

I can't search for subjects that only have a few words in it or a common word such as Red.
If I search for "Upper Red lake" it comes back with "the word red is to common and thrown out".

This is also true in many other searches. Search for "US Reel" throws out US and brings back anything with only reel.

I looked at all the search options in the admin but don't see anything to help me fix that.

How do I fix that search so people can use it to search with common words and smaller subjects?
