Abstract
Computerized systems and methods are provided for analyzing failed and successful search queries. In accordance with some embodiments, search records with character strings that are refinements of character strings of other search records are deemed related as belonging to a same user search. Minimum changed sections between character strings in related search records are determined. Correction pairs are created including the character sequences from the portions of the character strings containing the minimum changed sections. Frequencies of correction pairs in a pool of correction pairs are calculated, and the correction pairs appearing in the pool most frequently are stored in a correction log.
