I've implemented this on app engine:

http://www.miislita.com/term-vector/term-vector-3.html

limitations:
- need to store your own indexes,
- need to use task queue to work around 1MB put limit when creating /
updating indexes
- search is done in memory v. via queries
- might run out of time on extremely large searches (hasn't happened
yet)

benefits:
- you can use entire paragraphs as search queries
- automatic matching of *like* terms as a consequence of using this
approach

Another (simpler) way is described here:

http://googleappengine.blogspot.com/2010/04/making-your-app-searchable-using-self.html

limitations:
- Number of search terms is limited (to roughly 5).
- You have to make sure you are searching in a subset of the data with
less than ~200 results.

benefits:
- fast and easy to implement
