RediSearch是一个Redis模块,为Redis提供查询、二次索引和全文搜索,他的性能甚至比es还要高。
安装:
docker pull redislabs/redismod:preview
启动容器:
注意端口号不要和redis冲突了:
docker run -p 6399:6379 --name redismod -v /mydata/redismod/data:/data -d redislabs/redismod:preview

代码
package com.example.demo.Utils.RedisearchUtills;
import io.redisearch.*;
import io.redisearch.client.AddOptions;
import io.redisearch.client.Client;
import java.util.HashMap;
import java.util.Map;
public class redisearchMain {
public static void main(String[] args) {
Client client = new Client("student", "120.48.54.67", 6399);
// 定义一个索引模式
Schema schema = new Schema().addTextField("title", 5.0).addTextField("body", 1.0).addNumericField("star");
// 首次run 可以先注释掉
client.dropIndex();//先清除索引
// 创建索引
client.createIndex(schema, Client.IndexOptions.Default());
// 向索引中添加文档
Map<String, Object> fields1 = createDocument("任何视频", "新文档中不存在的内容将被保留。两者中存在的字段都会被覆盖", 1000);
Map<String, Object> fields2 = createDocument("任何通信", "新文档中不存在的内容将丢失", 500);
// client.addDocument("doc1", fields1);
// client.addDocument("doc2", fields2);
Document doc1 = new Document("doc1", fields1, 1.0, null);
Document doc2 = new Document("doc2", fields2, 1.0, null);
AddOptions options = new AddOptions().setNosave(false);
options.setLanguage("chinese");
client.addDocument(doc1, options);
client.addDocument(doc2, options);
Query query = new Query("内容").addFilter(new Query.NumericFilter("star", 0, 1500)).setWithScores().limit(0, 10);
SearchResult result = client.search(query);
result.docs.stream().forEach(docs->
System.out.println("====="+docs)
);
}
private static Map<String, Object> createDocument(String title, String body, Integer price){
Map<String, Object> fields = new HashMap<String, Object>();
fields.put("title", title);
