Hi all, I'm using lucene to store and index documents in a corpus for an university project and i need to implement the search for concordates of a given term, this means to find x terms before and after the given term in each document (for a variable x). I found the method TermPositions(Term t) for the IndexReader class which gives a TermPositions used to navigate inside a document, but i didn't understand what exactly nextPosition() gives out and how to use that result to find the closer terms (ie using the position for giving back the term at position position+1, -1, +2, -2, etc.). Is there some sort of "term navigator"?
Thanks, Mauro. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
