- We have only crawled US looking domains so as not to congest
international links. This makes the search engine somewhat incomplete.
- 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.
- Also, some docinfo pointers are corrupted. SB: I have patched the
code to account for most of these but I don't have tight bounds on the
extent of corruption.
- The performance is somewhat poor right now. This is partly due to
data going over NFS and antiquated hardware. However, we are
anticipating equipment donations from IBM and Intel to help with performance and increase our disk capacity so we can scale to 100
