问题 I have the mapping below and it works normally { "settings": { "index": { "number_of_shards": "5", "number_of_replicas": "0", "analysis": { "filter": { "stemmer_plural_portugues": { "name": "minimal_portuguese", "stopwords" : ["http", "https", "ftp", "www"], "type": "stemmer" }, "synonym_filter": { "type": "synonym", "lenient": true, "synonyms_path": "analysis/synonym.txt", "updateable" : true }, "shingle_filter": { "type": "shingle", "min_shingle_size": 2, "max_shingle_size": 3 } },
