[jira] [Commented] (LUCENE-3243) FastVectorHighlighter - add
position offset to FieldPhraseList.WeightedPhraseInfo.Toffs
[ https://issues.apache.org/jira/browse/LUCENE-3243?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13055347#comment-13055347 ]
Koji Sekiguchi commented on LUCENE-3243:
----------------------------------------
Thank you for the proposal and patch! I don't understand:
* What is the position offset? Isn't it just a position?
* Why is the position offset String?
* Why do you need setPositionOffset()? I don't understand the implementation of the method... it appends the argument position to the current position.

> Needed to return position offsets along with highlighted snippets when using FVH for highlighting.
> Using the ([LUCENE-3141|https://issues.apache.org/jira/browse/LUCENE-3141]) patch I was able to get the fragInfo for a particular Phrase search. Currently the Toffs(Term offsets) class only stores the start and end offset.
> To get the position offset, I added the position offset information in Toffs and FieldPhraseList class.
