elasticsearch.exceptions.RequestError: RequestError(400, 'mapper_parsing_exception', 'No handler for type [string] declared on field [texts]')
this
'index': 'analyzed' OR 'index': 'not_analyzed'
is an older elasticsearch version mapping and not needed.
All you need to do is use 'text' for analyzed string fields and 'keyword' for not_analyzed text fields, like this:
es = Elasticsearch("localhost:9200")request_body = { "settings": { "number_of_shards": 5, "number_of_replicas": 1 }, 'mappings': { 'examplecase': { 'properties': { 'tbl_id': {'type': 'keyword'}, 'texts': {'type': 'text'}, } } }}es.indices.create(index='example_index', body=request_body)see reference in Elastic docs here: https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping.html
See this. The index setting in your mapping is incorrectly configured. It is a mapping parameter and can be set to true or false only. You cannot set this within the properties parameter.
