Mark Miller commented on LUCENE-2939:
-------------------------------------
Fair enough (this setting is well before my time AFAIK) - but not my intent
with this issue - which is just to fix this little perf bug.
> Highlighter should try and use maxDocCharsToAnalyze in
> WeightedSpanTermExtractor when adding a new field to MemoryIndex

> huge documents can be drastically slower than need be because the entire
> field is added to the memory index
> this cost can be greatly reduced in many cases if we try and respect
> maxDocCharsToAnalyze
> the cost is still not fantastic, but is at least improved in many situations
> and can be influenced with this change
