| 23:47 | Change prefix search from O(N*M) to O(NlogM). The previous code linearly merged the doclists, so as the accumulated list got large, things got slow (the M term, a fucntion of the number of documents in the index). This change does pairwise merges until a single doclist remains. A test search of 't*' against a database of RFC text improves from 1m16s to 4.75s.
