> Analysis.jsp gives the incorrect results if you use "protwords.txt" or "stemdict.txt"
or the like.
> This is because this is now implemented with KeywordAttribute (so you can easily override
any stemmer etc).
> For example, if your schema had "foobars" in protwords.txt, analysis.jsp would show it
being stemmed to "foobar", even though this doesnt actually happen.
> The problem is that this jsp is downconverting the entire tokenstream to Token in between
processing, so it silently discards KeywordAttribute and you get the wrong result.
> Note: this issue isnt about *displaying* other attributes such as KeywordAttribute (which
would be a new feature). Its about not throwing them away so that the analysis actually represents
what happens.
