Stemming:

A fulltext search can stem words. If you search for run, you can get results for “ran” or “running”. Most fulltext engines have stem dictionaries in a variety of languages.

Weighted Search Results:

A full text search index allows for weighting search results to promote them or demote them in search results. This flexibility comes in handy for search administrators.
