Hi
You need to move the Document doc = new Document(); line to inside
your for loop. The code as it stands is adding data to a single
document instance that is being added to the index for each note, with
ever increasing amounts of data.
Or look at reusing Field instances with setValue() calls. That would
be more efficient but is a bit more complex - for your simple program
probably best to create a new Document for each note.
Tip: Luke is invaluable for seeing what an index holds, and a lot more.
