Table 7.4: Word Form Examples

We call this morpheme processing, and it is generally smarter than a traditional "stemming" algorithm. It doesn't just rip the end off a word, it actually checks to see if it could be a valid form of the search term. More information is available at https://docs.thunderstone.com/site/texisman/adjusting_linguistic_controls.html .

Notes: Thesaurus terms are also treated in the same manner. Words smaller than 4-5 characters will not be morpheme processed.
