Need to write a custom analyzer for ElasticsearchRepository findBy query

问题

I have an ES collection with following doc schema.

`

public class Address {
@Id
private String id;
private String name;
private String type;
private String city;
}

` My repository looks like as follows:

public interface NetworkElementsESRepository extends ElasticsearchRepository<Address, String> {
Address findByNameAndCity(String name, String city);}

I need to fetch all addresses with name= "B00/A3K/24" in a particular city using following Query. addressRepo.findByNameAndCity(Name,City) . I am not able to fetch the required addresses since name field has special characters ('/') and standard Analyzer seems to break the search string into different token. I need help with the custom Analyzer for ElasticsearchRepository.

First you need to either create the analyzer in Elasticsearch yourself, or by providing a settings file when creating the index with Spring Data Elasticsearch.

If you always need the custom analyzer for this field you can specify the analyzer in the @Field annotation you put on the name property either with analyzer or with searchAnalyzer.

If you only need the analyzer for the search with the repository, you should create a repository method annotated with @Query and add your custom query there.

See the Elasticsearch docs how such a query is built and Spring Data Elasticsearch docs for the use of the @Query annotation.
