Claim:
1. A computer-implemented method for identifying failed and successful search queries, comprising: retrieving, from a storage device, a first record including a first character string; retrieving a second record including a second character string; determining, by at least one processor, that the second character string is a refinement attempted by a user of the first character string; identifying at least a first sequence of characters of the first character string that differs from at least a second sequence of characters of the second character string; storing the first sequence of characters and the second sequence of characters as a pair in a database of stored pairs; calculating a frequency with which the pair containing the first sequence of characters and the second sequence of characters appears within the database of stored pairs; determining that the frequency exceeds a predetermined frequency threshold; and storing the pair in a correction log.
