According to the docs, 3.23.23 on up has Full Text search support.  View 
the info at: 

This will probably be the easiest way for you to go.

This is correct.

Verity is a good option for some things.  Its a great option if you are 
searching documents stored in the filesystem.  For info in the DB, its 
not so good in my opinion, because you have to create a collection 
outside the db by selecting data from the db.  This means that you query 
the external Verity collection, find matching records (if any) and then 
you have to go back to the database and query for those matching 
records.  Using a full text index, the queries work just like any other 
Select statement and you keep everything in the db.  Simpler and more 
efficient to my mind.
