The Morphological Analysis plugin integrates Russian and English morphology for java and lucene framework into elasticsearch. This plugin adds two new analyzers: “russian_morphology” and “english_morphology” and two token filters with the same names.
The demo.sh file shows a few examples of the analyzers behavior.
