Abstract
Apparatus, systems and methods for search filtering hash map are disclosed. Terms are designated as filtering terms, wherein at least one of the filtering terms includes only one component term, and at least one of the filtering terms includes a plurality of component terms in ordinal positions. A keyword hash map is generated for keywords, each keyword being one of the component terms and being mapped to one or more corresponding hashes in the hash map, and each corresponding hash having a corresponding level and a corresponding status, wherein each level corresponds to an ordinal position of its corresponding component term in a filtering term, and wherein each status designates its corresponding component term in the hash map as one of a filtering term or unfiltered term. The keyword hash map is stored in a memory storage system accessible by a data processing apparatus.
