Known Problems

1. We have only crawled US looking domains so as not to congest international links. This makes the search engine somewhat incomplete.

2. There has been some corruption in docid's for anchor hits. This results in some random looking matches (about 1 in 10). SB: I have tried to patch the code to account for this but there are still many problems.

This Search engine not work for now.
