In this paper we extend several well-known document listing problems to the case when documents contain a substring that approximately matches the query pattern. We study the scenario when the query string can contain a wildcard symbol that matches any alphabet symbol; all documents that match a query pattern with one wildcard must be enumerated. We describe a linear space data structure that reports all documents containing a substring Pin O(vertical bar P vertical bar + sigma root logloglog n + docc) time, where sigma is the alphabet size and docc is the number of listed documents. We also describe a succinct solution for this problem, as well as a solution for an extension of this problem. Furthermore our approach enables us to obtain an O (n sigma)-space data structure that enumerates all documents containing both a pattern P-1 and a pattern P-2 in the special case when P-1 and P-2 differ in one symbol.
