Currently, how are you indexing sentence boundaries? Are you placing sentences in distinct fields, leaving a position gap, or... what?
Ultimately it comes down to how you intend to query the data in a way that respects sentence boundaries. To put it simply, whay exactly do you care where the sentence boundaries are? Be specific, because that determines what your queries should look like, which determines what the indexed text should look like, which determines how the text should be analyzed. -- Jack Krupansky On Wed, Apr 15, 2015 at 8:12 AM, Shay Hummel <shay.hum...@gmail.com> wrote: > Hi Ahment, > Thank you for the reply, > That's exactly what I am doing.
