Subject [jira] [Issue Comment Edited] (LUCENE-3318) Sketch out highlighting based on term positions / position iterators
Date Sun, 24 Jul 2011 09:19:09 GMT

----------------------------------------------------------------

Some note from the TokenmStream policeman: The TokenStream must call clearAttributes() always
as first action unless it returns false (see docs), the positionIncrement is then also automatically
1. Also you should make the whole class PosTokenStream final, as you can/should never extend
it.

> Spinn off from LUCENE-2878. Since we have positions on a large number of queries already
in the branch is worth looking at highlighting as a real consumer of the API. A prototype
is already committed.
