Stemming

Stemming extends a search to cover grammatical variations on a word.  For example, a search for fish would also find fishing.  A search for applied would also find applying, applies, and apply.  There are two ways to add stemming to your searches:

1.   Check Stemming under Search features in the search dialog box to enable stemming for all of the words in your search request.  (By default, the box is checked.) Stemming does not slow searches noticeably and is almost always helpful in making sure you find what you want.

 

2.   To add stemming selectively, add a ~ at the end of words that you want stemmed in a search.  Example: apply~
 

The stemming rules included with dtSearch are designed to work with the English language.  These rules are in the file stemming.dat.   To implement stemming for a different language, or to modify the English stemming rules that dtSearch uses, edit the stemming.dat file.   See the stemming.dat file for more information.
