Question

我是Elasticsearch的新手。我们正在使用Elasticsearch 5.0.1，我正在尝试创建索引，如下所示。我确实在这里查看了弹性搜索和一些帖子的文档，但是无法使用以下所需的设置创建索引

                "search_analyzer": "analyzer_startswith"
            }
        }
    }
}
}

但我收到以下错误，请你帮我解决一下。

{
"error": {
    "root_cause": [{
            "type": "mapper_parsing_exception",
            "reason": "Mapping definition for [sample1] has unsupported parameters:  [search_analyzer : analyzer_startswith] [analyzer : autocomplete]"
        }
    ],
    "type": "mapper_parsing_exception",
    "reason": "Failed to parse mapping [sample]: Mapping definition for [sample1] has unsupported parameters:  [search_analyzer : analyzer_startswith] [analyzer : autocomplete]",
    "caused_by": {
        "type": "mapper_parsing_exception",
        "reason": "Mapping definition for [sample1] has unsupported parameters:  [search_analyzer : analyzer_startswith] [analyzer : autocomplete]"
    }
},
"status": 400
 }

Answer 1

keyword类型不支持分析器。将类型更改为text，您应该很高兴。

Elasticsearch版本5.0.1，搜索分析无法正常工作。
