软件简介

redis-search 是一款基于 Redis 的高效搜索组件

特点

  • 实时更新搜索索引
  • 高效
  • 分词搜索和逐字匹配搜索
  • 别名搜索
  • 支持 ActiveRecord 和 Mongoid
  • 暂时只能用一个字段做为排序条件
  • 中文同音词，汉语拼音搜索支持
  • 可以用一些简单的附加条件组合搜索

快速启动

  redis:
    image: redislabs/redisearch:latest
    container_name: redis
    volumes:
      - ./depoly/components/redis/data:/data
    environment:
      TZ: Asia/Shanghai
    restart: always
    sysctls:
      net.core.somaxconn: 1024
    command: redis-server --requirepass 123456 --appendonly yes --loadmodule /usr/lib/redis/modules/redisearch.so --loadmodule /usr/lib/redis/modules/rejson.so
    ports:
      - 6379:6379

redisearch 镜像已带了rejson模块,启动时加载进去则可

查询语句

FT.SEARCH idx "@title|body:(hello world) @url|image:mydomain"
SQL表达式 对应Redis表达式 描述
WHERE x='foo' AND y='bar' @x:foo @y:bar for less ambiguity use (@x:foo) (@y:bar)
WHERE x='foo' AND y!='bar' @x:foo -@y:bar
WHERE x='foo' OR y='bar' (@x:foo)|(@y:bar)
WHERE x IN ('foo', 'bar','hello world') @x:(foo|bar|"hello world") quotes mean exact phrase
WHERE y='foo' AND x NOT IN ('foo','bar') @y:foo (-@x:foo) (-@x:bar)
WHERE x NOT IN ('foo','bar') -@x:(foo|bar)
WHERE num BETWEEN 10 AND 20 @num:[10 20]
WHERE num >= 10 @num:[10 +inf]
WHERE num > 10 @num:[(10 +inf]
WHERE num < 10 @num:[-inf (10]
WHERE num <= 10 @num:[-inf 10]
WHERE num < 10 OR num > 20 @num:[-inf (10] | @num:[(20 +inf]
WHERE name LIKE 'john%' @name:john*

索引操作

FT.DROPINDEX idx

FT.CREATE idx ON JSON PREFIX 1 blog:post: SCHEMA $.sku AS sku_text TEXT
FT.CREATE idx1 ON JSON PREFIX 1 blog:tag: SCHEMA $.sku AS sku_text TEXT

FT.CREATE idx ON JSON PREFIX 1 blog:post: SCHEMA $.sku AS sku_tag TAG


JSON.SET blog:post:1 $ '{"sku":"a,b,c"}'
JSON.SET blog:tag:1 $ '{"sku":"a,b,c"}'


FT.SEARCH idx '@sku_text:a,b,c'


FT.CREATE userIdx ON JSON SCHEMA $.user.name AS name TEXT $.user.tag AS country TAG
JSON.SET myDoc $ '{"user":{"name":"John Smith","tag":"foo,bar","hp":1000, "dmg":150}}'
FT.SEARCH userIdx '@name:(John)'
