Hi,
I have to build a Terms-Document-Matrix to be able to do some Matrix
operations on it.
the Matrix should look like (I hope this will be displayed correctly):
term1 term2 term3 term4 ...
----------------------------------
Doc1 freq freq freq freq
Doc2 freq...................
Doc3 .......................
Doc4 .......................
.
.
.
I tried that by using IndexReader.terms() and IndexReader.TermDocs(term)
to get all the terms and the document-numbers which contain them.
As you can imagine, the TermEnumeration-Object has become to big to fit
into memory.
Is there an "easy" way to get the Terms one by one (without writing my
own IndexReader)?
