Seems like you should allow both double and single quotes, and it would be
cool if unquoted strings that were phrases ranked higher.

Would, say, a period at the end of a sentence bump the word position
counter?  What about stop words?  I assume they wouldn't count in the word
position.

So searching for 'Berkeley University' find a document that contained this:

...many fast food restaurants can be found in Berkeley.  A University is
located there, also....

Are the positions stored null terminated binary string or in ASCII?

People would love phrase searching.
