新建站点步骤东莞seo优化团队
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
实验目的
利用redis search 实现文本搜索功能

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
