Mark Miller commented on LUCENE-794:
------------------------------------
I switched to accepting an analyzer and a field name. I need the field name
anyway for the MemoryIndex.
I agree that modifying MemoryIndex was horrible and I have removed that
dependency (just did it as a 'quickfix').
I used the CachedTokenStream anyway to avoid analyzing twice (once for
MemoryIndex and again for Highlighter use. Thanks for the idea...shows how
bright I am having missed it <g>).
I removed all of the 1.5 code.
The code is probably fairly usable right now then. I think synonyms work fine
unless a case does exist like you suggested.
So I suppose we have 4 options:
1. I extend and polish the code (needs more test cases, most of mine where
written using my query parser) and it is used independently for full document
highlighting based on spans. (I would like to add google cache like coloring)
2. The code is either merged with the existing highlighter or gutted to create
a single highlighter that can fragment based on spans or based on the original
term based approach.
3. The code is ignored and someone else starts fresh adding span support to the
existing highlighter.
4. The code languishes in purgatory and we await the unknown.
