Re: position padding instead of positionIncrementGap
Paul,
Thanks for responding!
But it sounds like it will work in a single value (token stream). How to
implement padding across several text values (separate token streams)? Can
we pass the last position from one token stream to the following?

RE: position padding instead of positionIncrementGap

Hi,
So you want to use a fixed “start” position for each value instead of a gap? That’s impossible with patching IndexWriter. Alternatively write a single “appending” tokenstream that concat its sub-streams and assigns a corresponding gap depending on actual position.

That's too simple, so what is the real question?

Hello! Devs,
I'm sure it's discussed many times or were in it air. If I have a few 3-tokens values in a multivalued field, how I can assign positions:
0,1,2...10,11,12,...20,21,22...
instead of
0,1,2, 12,13,14, 24,25,26.. giving that positionIncrementGap=10 ?
