Robert Muir commented on LUCENE-2939:
-------------------------------------
Maybe the setting is already there, but I think we should remove it: I don't
think its the best measure.
We can instead replace it with a max # tokens setting, which is more intuitive,
easier to implement,
and consistent with how other things are limited (e.g. the old IW setting and
the new
LimitTokenCountFilter).
> 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
