Previous work created several functions in the Hyper Dictionary. The Hyper Dictionary has searching functions with English words, Indo-European roots, English prefixes, English synonyms, stems of English words, and interim transitional words (see Table 1). In 2003, researchers changed the operating system from Windows to Linux, and added an application for learning English words and Indo-European roots called a Hyper Tool (see Table 1).
These searching methods are front matching.
