ECH's goal for the search engine in the web database is that, if a user searches for "fat", s/he will get results including fat, fatten, fattening, fatty.

Our current settings, and our policies for adding inferred glosses, seem to be accomplishing this nicely. An entry which has "fatty" in its def is found by a search for "fat", because it also has an inferred gloss "fat".

Searching for "fat*" also returns defs including fat, fatten, fattening, fatty ... but also fatal, fathom, father.
