Any data in the database can be included or excluded from a search by altering form input. The search indexes are built primarily by user submissions and supplemented with a web crawler that searches unspecified sources for new page announcements. The user browses through a series of cascading menus in the branching subject hierarchies to locate the desired site listings. The search engine uses standard Boolean operators and supports nested logic. Proximity searches can be done on bound phrases.
Prefixes allow search terms to be spedifically required or excluded from the result.
There is no option to limit or enhance search results.
