elasticsearchHow can I use the Russian Analyzer in Elasticsearch?
The Russian Analyzer in Elasticsearch can be used to analyze and tokenize Russian language texts. It is a part of the Elasticsearch's Analysis API, which provides a framework for customizing language analysis.
To use the Russian Analyzer in Elasticsearch, you need to specify the name of the analyzer in the mapping of the index. For example:
PUT my_index
{
"mappings": {
"properties": {
"title": {
"type": "text",
"analyzer": "russian"
}
}
}
}
This will set the title field of the index to use the Russian Analyzer.
You can then use the analyzed tokens in search queries. For example:
GET my_index/_search
{
"query": {
"match": {
"title": {
"query": "привет"
}
}
}
}
This will search for documents that contain the token привет
(which will be tokenized into привет
by the Russian Analyzer).
