1.什么是Redis Search？

RedisSearch 是一个基于 Redis 的搜索引擎模块，它提供了全文搜索、索引和聚合功能。通过 RedisSearch，可以为 Redis 中的数据创建索引，执行复杂的搜索查询，并实现高级功能，如自动完成、分面搜索和排序。利用 Redis 的高性能特点，RedisSearch 可以实现高效的搜索和实时分析。对于微服务架构来说，RedisSearch 可以作为搜索服务的一部分，提供快速、高效的搜索能力，对于提高用户体验和性能具有重要的意义。

2.环境搭建

Docker Compose

version: '3'
services:redis:image: redis/redis-stackcontainer_name: redisports:- 6379:6379redis-insight:image: redislabs/redisinsightcontainer_name: redis-insightports:- 8001:8001

Run following command:

docker-compose up -d

3.代码工程

}

package com.et.redis.hash;import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;import java.util.Optional;@Repository
public interface PersonRepository extends CrudRepository<Person, String> {Optional<Person> findByName(String name);Optional<Person> searchByLastName(String name);
}

@Document 方式

package com.et.redis.document;import com.redis.om.spring.annotations.Document;
import com.redis.om.spring.annotations.Indexed;
import com.redis.om.spring.annotations.Searchable;
import org.springframework.data.annotation.Id;@Document

4.测试

启动Spring boot应用

测试hash方式

插入一个实体

查询

    模糊查询redis数据（*rab*）

查看redis数据库数据

redis数据库模糊查询

测试json document方式

同样的方式插入json文档，然后在你redis数据库里面查看
