A modified Boyer-Moore searching algorithm used within an E-mail filtering system for detecting the presence of a plurality of target band strings during a single traversal of the character data to be searched. A single jump table for the combined set of strings for which a search is being made is used. A hierarchical match table starting with the possible terminating letters of strings for which a search is being made is traversed to identify any strings as they are encountered.
