Method of database searching

The present invention is a method of database searching. First, a language is selected and elements received. The system is searched to identify a unit number associated with each element, which is linked to a data unit containing morphological variants of the element. If none are identified, the element is broken into sub-textual units that may contain a prefix, compound-prefix, and/or suffix along with a primary element. A unit number is then obtained for the primary element. If this does not result in a match, the elements may be saved in a database for further linguistic development. A unit number associated with each matched element is then chosen, and the elements contained in the data units linked to the unit numbers are compared to a database index. If an element is associated with multiple unit numbers, this process is repeated until all data units have been compared to the database.
