You have to create a new Field class with "new Field(...", i.e.
replace doc.add(Field.Text with doc.add(new Field(...

I appreciate everyone's responses.
I guess the main advantage of putting lucene's index into a RDBMS is for
flexibility of queries. Personally, I rather use a RDBMS for results than
lucene because I am more experienced with SQL queries than using Java.
Does anyone have a simple example of using

My gut feel is that, with 150 records, using Lucene is overkill. This
assumes that your database already exists. You'd have to extract the data
from the DB, store it in a lucene index, then worry about keeping them
synchronized.
I'd suggest, though, that the fastest way to satisfy yourself about

Look at IndexFiles.java in src/demo/org/apache/lucene/demo. It uses this
call for adding two fields. You should be able to build this with "ant

At present, we have two indexes which we search. The primary index

Search the mail archives for "date" and "sort" and you'll get many, many

the Sort class.
