spell check and singular/plural check in VB/Java/SQL

Im basically trying to do a simple search utility in my 开发者_如何学PythonSQL Server database.

Need to search for "different form of words" typed by the user including spell check, singular/plural. Having the present/past/future tense also considered will be a super-to-have feature.

Can you help me find API(s) for each of these or all in one. Im only looking for open Source or Freeware.

Language Im looking for is either VB or Java. Im kind of new to Java and I looked at Lucene and wasnt sure if it will help me.

Why not use SQL Server Full-Text Search?
