analyzing a single elasticsearch field in different ways-CodePudding

I want to know how can I analyze an elasticsearch field with two different analyzers at the same time. I am creating an elasticsearch plugin so, I need the java code to implement the same.

CodePudding user response：

you can use the multi-fields to achieve the same. Refer multiple analyzer section in the document with example.

CodePudding user response：

You can use Create Index API in java code for creating index with multi field

CreateIndexRequest request = new CreateIndexRequest("twitter");

Map<String, Object> email_second = new HashMap<>();
email_second.put("type", "text");
email_second.put("analyzer", "custom_standard");

Map<String, Object> email = new HashMap<>();
email.put("type", "text");
email.put("analyzer", "standard");
email.put("fields", "email_second");


Map<String, Object> properties = new HashMap<>();
properties.put("email", email);
Map<String, Object> mapping = new HashMap<>();
mapping.put("properties", properties);
request.mapping(mapping);

CreateIndexResponse createIndexResponse = client.indices().create(request, RequestOptions.DEFAULT);

you can access first email field with email and second with email.email_second name.
