elasticsearch analysis morphology

elasticsearch-analysis-morphology

Plugin for ElasticSearch (8.4.1) implements the analyzer for Russian and English languages, the dictionaries of the project http://aot.ru are used. The original plugin was taken from here https://github.com/imotov/elasticsearch-analysis-morphology which in turn uses russian_morphology and english_morphology from the Russian Morphology for Apache Lucene project https://github.com/AKuznetsov/russianmorphology The plugin adds two analyzers and token filter: "russian_morphology" and "english_morphology"

Elasticsearch

When creating an index, we specify the settings indicating the analyzer and create a mapping based on the settings. Example

 PUT /products
{
    "settings": {
        "index": {
            "analysis": {
                "analyzer": {
