I found some people asking if anyone had made one in Lucene. Didn't seem so. Basically, the Lucene indexes are inverted, meaning they go from terms to documents. I need to find the list of terms found in a document. The reason is I have a lot of documents that are attachments and I don't want to be parsing them again and again, and I need to get the terms out of them for classification purposes.

Thanks.

Hi,

what is your actual question?
Btw, if you are storing the term vector in your documents (enabled via an option), you can retrieve it later via IndexReader#getTermFreqVectors(int docNumber)

Yeah I want to be able to get the terms and frequencies found in a document.

I am kind of confused about what you didn't get in my original question. I have a bunch of attachments associated with an entity. I need to index the text in the attachments. Then I need to know what terms were found later. I don't want to have to go fetch all the attachments and parse them again. Kinda simple.

Looks like your solution will do that for me. Thanks.
