Thanks for the note. But I think you misunderstand a bit (or I do :-).

You're right, it's unecessary unless you want to search on both (so
index both), as you said in your other message

There is no need for that. A single field that is both indexed and
stored will give you the same ting.

Hi,
You'd better use 2 fields, one analysed and not stored, and the other
one only stored.
So you perform the query on the analysed field and present the other
field (not stemmed) in the result.

Do you want to search for the unstemmed term, or just be able to retrieve it?
When you retrieve a document, you get the un-analyzed original fields.
If you want to index both the stemmend and unstemmed terms, the
easiest way is to add the field twice (the second time using a
different field name)
Hi,

What do you exactly mean by features vector? You are referring to the

Hits doesn't keep track of all 100,000 matches, only the first 100.
It dynamically collects more matches if it needs to.

Hi,
I am not sure whether my understanding is correct.
In your application, A concept "document" first should be defined as a class
in the ontology? Then, each document is an instance of this class. It uses
its contents as its features. Also, the related concepts will be added into
the feature ve
Its for both, onto + contents (Word, Pdf, PPT, all time the same candidates).
The main disadvantage of this approach is that "main" nodes in the ontology
have to be defined.
