Subject [jira] Commented: (SOLR-2051) analysis.jsp is incorrect for protWords etc
Date Mon, 16 Aug 2010 18:44:17 GMT

Robert Muir commented on SOLR-2051:
-----------------------------------

you can reproduce this easily / verify it is now correct by going to the analysis.jsp, turning
on verbose output, and entering "dontstems" for field type "text", as its already in the protwords.txt

without the patch you will see it being stemmed.

> 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.
