Words that need protection from stemming, i.e., protwords.txt

[David Woodward <dw...@loc.gov>]

Hi.

Any good protwords.txt out there?

In a fairly standard solr analyzer chain, we use the English Porter analyzer like so:

<filter class="solr.EnglishPorterFilterFactory" protected="protwords.txt"/>

For most purposes the porter does just fine, but occasionally words come along that really don't work out to well, e.g.,

"maine" is stemmed to "main" - clearly goofing up precision about "Maine" without doing much good for variants of "main".

So - I have an entry for my protwords.txt. What else should go in there?

Thanks for your ideas,

Dave Woodward
