Abstract
A system monitors access to a computer file via a dynamically changeable non-heterogeneous collection load balanced across two hash tables. User activity is monitored on a target device to detect a user entered pattern including a wildcard character. A server in communication with the target device, receives the user entered pattern, selects one of the two hash tables, and calculates an index for the selected hash table based on the user entered pattern. The index is used to access the selected hash table to receive a stored pattern. The hash tables each have a plurality of entries, and each entry includes a list of one or more patterns that have the same hash index but different pattern values sorted by length in characters from longest to shortest.
