PUT _all { "settings": { "analysis": { "analyzer": { "my_analyzer": { "tokenizer": "ngram_one_word" } }, "tokenizer": { "ngram_one_word": { "type": "ngram", "min_gram": 1, "max_gram": 16, "filter": [ "lowercase" ] } } } } } { "error": { "root_cause": [ { "type": "invalid_index_name_exception", "reason": "Invalid index name [_all], must not start with '_', '-', or '+'", "index_uuid": "_na_", "index": "_all" } ], "type": "invalid_index_name_exception", "reason": "Invalid index name [_all], must not start with '_', '-', or '+'", "index_uuid": "_na_", "index": "_all" }, "status": 400 }
