Hoss Man commented on LUCENE-5697:
----------------------------------
1) Lucene 3.5 is pretty old.
2) At first glance, it sounds like the problems you are describing could simply
be due to a disconnect between how your searches are executed vs how you are
using the highlighter code.
w/o specific example code or a reproducible test case, there's really no way to
tell if what you are describing is a genuine bug or a missunderstanding of the
API.
3) there multiple highlighters available, and a *lot* of different ways to
configure them, so even if there is a bug, w/o more specifics there really
isn't enough info here to try and diagnose _where_ the bug is, let alone _what_
the bug is.
---
can you please provide some code (ideally a stand alone JUnit test using the
lucene test-framework) demonstrating the problem?

> Key: LUCENE-5697
> URL: https://issues.apache.org/jira/browse/LUCENE-5697
> Project: Lucene - Core
> Issue Type: Bug
> Components: modules/highlighter
> Environment: DocFetcher 1.1.11 on Win 7(64) pro
> Reporter: Martin Schoenmakers
>
> In DocFetcher, which uses Lucene v3.5.0, we stumbled on a bug. The lead of
> DocFetcher has investigated and found the problem seems to be in Lucene. I do
> not know if this bug has been fixed in a later Lucene version.
> Issue:
> We use "proximity search": search on multiple words in a directory with about
> 300 PDF files.
> E.g. search for "wordA wordB wordC"~50, i.e. three words within 50 words
> distance of each other. The resulting documents are correct. But the
> highligted text in the document is often missing.
> If the words are in the SAME order as in the search AND on the SAME page,
> then the higlight works correct. But if the order of the words is different
> from the search (like "wordA wordC wordB" OR the words are not on the same
> page, then that text is not highlighted.
> As we use the proximity search on multiple words often, it severely degrades
> the usability.
