Elasticsearch实现全文检索

搜索步骤

关键词 es 匹配 满足条件返回id集合 --> 通过id集合,查询mysql/mongodb数据库得到数据列表

数据初始化:

设计domain 想当于在Elasticsearch中创建需全文查询的库和表

/**
 * 目的地搜索对象
 */
@Getter
@Setter
@Document(indexName="wolf2w_destination",type="destination")
public class DestinationEs implements Serializable {
   

    public static final String INDEX_NAME = "wolf2w_destination";
    public static final String TYPE_NAME = "destination";
    @Id
    //@Field 每个文档的字段配置（类型、是否分词、是否存储、分词器 ）
    @Field(store=true, index = false,type = FieldType.Keyword)
    private String id;  //攻略id

    @Field(index=true,store=true,type = FieldType.Keyword)
    private String name;

    @Field(index=true,analyzer="ik_max_word",store=true,searchAnalyzer="ik_max_word",type = FieldType.Text)
    private String info;
}
