Hello,
./index functions fairly well now. However, searchd and s.cgi on Alphas seem
to have some communication problems. When query is sent via s.cgi, it obtains
the quantity of results from searchd, but fails to get the documents. Boths
ides fall into blocking recv(). s.cgi starts listening for documents whiles
earchd still expects some statistics from the client. Here is gdb output:
./s.cgi:
