redisearch php,Redis模块之RediSearch的简单使用

说明：安装的Redis服务器必须为 4.0 以上版本，通过info命令查看

127.0.0.1:6379> INFO

redis_version:4.0.2

一、安装 RediSearchgit clone https://github.com/RedisLabsModules/RediSearch.git

cd RediSearch/src

make all

# Assuming you have a redis build from the unstable branch:

/path/to/redis-server --loadmodule ./redisearch.so

二、启动服务www@TinywanAliYun:/usr/local/redis4.0/etc$ /usr/local/redis4.0/bin/redis-server --loadmodule /home/www/build/RediSearch/src/redisearch.so

22886:C 15 Nov 16:54:07.255 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

22886:C 15 Nov 16:54:07.255 # Redis version=4.0.2, bits=64, commit=00000000, modified=0, pid=22886, just started

22886:C 15 Nov 16:54:07.255 # Configuration loaded

22886:M 15 Nov 16:54:07.256 # Creating Server TCP listening socket *:6379: bind: Address already in use

可以动态加载www@TinywanAliYun:/usr/local/redis4.0/etc$ redis-cli

127.0.0.1:6379> MODULE LOAD /home/www/build/RediSearch/src/redisearch.so

配置文件加载：vi /usr/local/redis4.0/etc/redis.conf

#文件底部加入

loadmodule /home/www/build/RediSearch/src/redisearch.so

重启服务器sudo systemctl restart redis

三、使用

(1)使用字段和权重创建索引(默认权重为1.0)127.0.0.1:6379> FT.CREATE myIdx SCHEMA title TEXT WEIGHT 5.0 body TEXT url TEXT

OK

(2)将文档添加到索引127.0.0.1:6379> FT.ADD myIdx doc1 1.0 FIELDS title "hello world" body "lorem ipsum" url "http://redis.io"

OK

(3)搜索索引127.0.0.1:6379> FT.SEARCH myIdx "hello world" LIMIT 0 10

1) (integer) 1

2) "doc1"

3) 1) "title"

2) "hello world"

3) "body"

4) "lorem ipsum"

5) "url"

6) "http://redis.io"

注意：输入预计是有效的utf-8或ascii。目前引擎无法处理宽字符unicode。

(4)删除索引127.0.0.1:6379> FT.DROP myIdx

OK

(5)添加和获取自动完成建议127.0.0.1:6379> FT.SUGADD autocomplete "hello world" 100

OK

127.0.0.1:6379> FT.SUGGET autocomplete "he"

1) "hello world"
