1.在使用ES之前就应该把mapping指定写好,官方文档写的很详细 You can only find that which is stored in your index. In order to make your data searchable, your database needs to know what type of data each field contains and how
三、Mapping parameters https://www.elastic.co/guide/en/elasticsearch/reference/6.2/mapping-params.html带*是常用的字段属性
elasticsearch入门使用 Mapping + field type字段类型 Elasticsearch Reference [6.2] ? Mapping 参考官方英文文档https:///guide/en/elasticsearch/reference/current/mapping.html Mapping 是定义文档及其包含的字段如何存储和编制索引的过程,每个索引都有一个映射类型,用于确定文档将如何编制索引。 Meta-fields 包括文档的_...

简介:Elasticsearch Mapping之字段类型(field datatypes) ElasticSearch支持如下数据类型: string (字符串类型) 字符串类型包含text与keyword两种类型。 text 文本类型,在索引文件中,存储的不是原字符串,而是使用分词器对内容进行分词处理后得到一系列的词根,然后一一存储在index的倒排索引中。
