Stemming demonyms in Solr (Russian => Russia)

Question

Trying to match queries containing "russia" or "russian" to "Russian Federation" using Solr (as well as other country demonyms, such as "american", "syrian" etc).

What is a good way to handle this without adding synonyms for each country, and without doing much stemming on other words?

Stemming sounds like the right solution here. Why are you avoiding stemming? — femtoRgon, Mar 19 '14 at 22:58

Turns out stemming was the right approach, but the Porter stemmer was too aggressive for some terms.

The KStemFilterFactory is less aggressive and worked well.
