adding analyser in ElasticSearch field of type array

Question

I have an elastic search object in which one field is an array type. now i want to apply a different analyser than standard default one. when i pass analyzer in index definition, it is throwing error. how can i do this?

In the below example, skills contains an array of values. all i want is to apply different analysers and see results. how can i achieve that?

 "skills": { "type": "object", "analyzer": "simple" }, "profile": { "type": "text", "analyzer": "simple" }, "job_title": { "type": "text", "analyzer": "simple" },

Getting below error:

{ "error": { "root_cause": [ { "type": "mapper_parsing_exception", "reason": "Mapping definition for [skills] has unsupported parameters: [analyzer : simple]" } ], "type": "mapper_parsing_exception", "reason": "Failed to parse mapping [_doc]: Mapping definition for [skills] has unsupported parameters: [analyzer : simple]", "caused_by": { "type": "mapper_parsing_exception", "reason": "Mapping definition for [skills] has unsupported parameters: [analyzer : simple]" } }, "status": 400 }

It would help to see the error you're getting and the different commands you're running — Val

You can only define and analyzer for text fields, not object ones — Val

There's no dedicated array data type in ES. If skills is an array of keywords, you can use type:text & analyzer:simple.

Tip: if you'd like to quickly iterate on the effects of different analyzers, you can use the _analyze endpoint without having to drop/adjust/reindex each time:

GET _analyze { "text": [ "lorem", "ipsum", "123abc" ], "analyzer": "simple" }
