Comment(by sehaj.sk):

 This patch provides matching modes for QueryParser and TermGenerator.
 The mode for indexing can have following 4 values :[[BR]]
 1. STEM_NONE: Don't index any stemmed word[[BR]]
 2. STEM_SOME: Index both stemmed as well as full (non-stemmed)
 words.(note: prefix "Z" is present in front of the stemmed words). [[BR]]
 3. STEM_ALL:  Index only stemmed words.(note: stemmed words DONT have "Z"
 prefix).[[BR]]
 4. STEM_ALL_Z:  Index only stemmed words. (note: stemmed words have "Z"
 prefix).[[BR]]

 Correspondingly a new stemming strategy QueryParser::STEM_ALL_Z has been
 introduced.
