全面解析MeiliSearch及其Go语言实现

前言

随着互联网的发展和数字化进程的加速，无论是企业还是个人用户，都需要面对海量的信息。在这个背景下，搜索技术的重要性日益凸显。MeiliSearch 是一款开源搜索引擎，它的出现为开发者提供了一个高效、灵活的选择。本文将从多个角度探讨 MeiliSearch 的特性、使用方法及其实现原理，并通过 Go 语言示例展示如何构建一个高性能的搜索系统。

一、MeiliSearch 特性

MeiliSearch 之所以受到欢迎，主要是因为它具有以下几个关键特性：

• 易用性：MeiliSearch 的设计初衷就是简化搜索集成流程，无论是安装、配置还是使用都非常直观。
• 高性能：它采用了高效的搜索算法和数据结构，能够在毫秒级内返回搜索结果。
• 高度可定制性：用户可以根据具体需求调整搜索算法的权重，甚至定义同义词和停用词等。
• 多语言支持：MeiliSearch 内置了对多种语言的支持，这对于全球化的产品来说非常有用。
• 实时性：索引更新几乎是实时的，这意味着任何新的数据都可以立刻被搜索到。

1.1 核心功能

文档索引

索引是搜索引擎的核心，MeiliSearch 支持文档级别的索引，这意味着每个独立的条目都可以被单独索引。通过 RESTful API，你可以轻松地添加、删除或更新索引中的文档。

排序与过滤

MeiliSearch 允许你在搜索查询中指定排序规则和过滤条件，这使得你可以根据用户的偏好或业务逻辑来组织搜索结果。

同义词与停用词

为了提高搜索的准确性，MeiliSearch 支持自定义同义词和停用词。同义词可以用来处理多义词或多写法的情况，而停用词则有助于减少噪音词汇的影响。

高级搜索语法

除了基本的全文搜索之外，MeiliSearch 还支持布尔搜索、模糊搜索等多种搜索语法，这让搜索查询变得更加灵活和强大。

1.2 技术栈

MeiliSearch 是基于 Rust 语言开发的，这赋予了它极高的性能和稳定性。Rust 的内存安全特性也使得 MeiliSearch 在处理大量数据时更加可靠。

二、安装与设置

2.1 前提条件

• 一台运行着 Linux、macOS 或 Windows 的计算机。
• Docker。
• Go 语言环境（推荐版本：1.17 或更高）。

2.2 安装过程

通过 Docker 安装

如果你的机器上已经安装了 Docker，那么可以通过以下命令快速启动 MeiliSearch：

docker pull getmeili/meilisearch
docker run -it --rm -p 7700:7700 -e MEILI_ENV='development' -e MEILI_MASTER_KEY='3EX4QpUfpqX6XfOIks-qWg6tvpQxdWmr7CxHUN4GgaA' -e MEILI_SCHEDULE_SNAPSHOT=60 -v /user/local/src/meilisearch/data:/meili_data getmeili/meilisearch:v1.9

docker run: 运行一个容器。
-it: 以交互模式 (interactive) 运行容器，并分配一个伪输入终端 (TTY)。
--rm: 当容器停止时自动删除容器。
-p 7700:7700: 将主机的 7700 端口映射到容器内的 7700 端口，这样可以从外部网络访问容器内的服务。
-e MEILI_ENV='development': 设置环境变量 MEILI_ENV 为 development，这意味着 MeiliSearch 将以开发模式运行。
-e MEILI_MASTER_KEY='3EX4QpUfpqX6XfOIks-qWg6tvpQxdWmr7CxHUN4GgaA': 设置主密钥 (MEILI_MASTER_KEY)，用于管理所有 API 调用。
-e MEILI_SCHEDULE_SNAPSHOT=60: 设置定期快照的时间间隔为 60 秒，这表示每分钟 MeiliSearch 将会创建一个快照。
-v /user/local/src/meilisearch/data:/meili_data: 将主机上的 /user/local/src/meilisearch/data 目录挂载到容器内的 /meili_data 目录，这样可以持久化 MeiliSearch 的数据。
getmeili/meilisearch:v1.9: 指定要运行的 Docker 镜像，标签为 v1.9。

这条命令将会下载最新的 MeiliSearch 镜像并启动一个容器，在你的机器上开放 7700 端口。

本地安装

如果你希望直接在本地安装 MeiliSearch，可以使用以下命令：

curl -L https://install.meilisearch.com | sh

这条命令会下载并安装 MeiliSearch 到你的系统中。

2.3 配置与管理

API 密钥

为了保护你的数据安全，MeiliSearch 允许生成 API 密钥来限制对索引的访问。你可以通过 API 创建不同的密钥，并为每个密钥分配不同的权限。

curl 'http://localhost:7700/apikeys' -X POST \
    -H 'Content-Type: application/json' \
    -d '{"description":"example API key", "actions":["search"], "indexes":["*"]}'

索引管理

MeiliSearch 通过索引来组织数据。你可以创建多个索引，每个索引对应不同类型的数据。创建索引的命令如下：

curl 'http://localhost:7700/indexes' -X POST \
    -H 'Content-Type: application/json' \
    -d '{"uid":"myFirstIndex"}'

一旦索引被创建，你就可以开始向其中添加数据了。

日志与监控

MeiliSearch 提供了详细的日志记录功能，这对于调试和维护非常有帮助。你可以通过查看容器的日志来了解 MeiliSearch 的运行状态：

docker logs 

三、使用 Go 语言与 MeiliSearch 交互

Go 语言以其简洁的语法、高效的性能和良好的并发支持而闻名，这使得它成为与 MeiliSearch 进行交互的理想选择。下面是一些使用 Go 语言操作 MeiliSearch 的示例。

3.1 示例代码

3.1.1 创建索引

package main

import (
	"fmt"
	"github.com/meilisearch/meilisearch-go"
)

func main() {
	// 创建 MeiliSearch 客户端实例
	client := meilisearch.NewClient(
		meilisearch.ClientConfig{
			Host:   "http://localhost:7700",
			APIKey: "3EX4QpUfpqX6XfOIks-qWg6tvpQxdWmr7CxHUN4GgaA", // 如果使用了API密钥
		},
	)

	// 创建索引
	task, err := client.CreateIndex(&meilisearch.IndexConfig{Uid: "movies"})
	if err != nil {
		fmt.Println("Error creating index:", err)
		return
	}

	fmt.Printf("Created index response : %+v\n", *task)
}

3.1.2 搜索文档

为了方便大家有大量数据，这里使用官方提供的 movie 数据，大家点击下载使用。

package main

import (
	"encoding/json"
	"fmt"
	"github.com/meilisearch/meilisearch-go"
	"log"
	"os"
)

func main() {
	// 创建 MeiliSearch 客户端实例
	client := meilisearch.NewClient(
		meilisearch.ClientConfig{
			Host:   "http://localhost:7700",
			APIKey: "3EX4QpUfpqX6XfOIks-qWg6tvpQxdWmr7CxHUN4GgaA", // 如果使用了API密钥
		},
	)

	// 搜索文档
	resp, err := client.Index("movies").Search("Star Wars", &meilisearch.SearchRequest{Limit: 2})
	if err != nil {
		log.Fatalf("Error searching: %v", err)
	}

	// 输出搜索结果
	for _, movie := range resp.Hits {
		fmt.Printf("%+v\n", movie)
	}
	// map[genres:[Adventure Action Science Fiction] id:11 overview:Princess Leia is captured and held hostage by the evil Imperial forces in their effort to take over the galactic Empire. Venturesome Luke Skywalker and dashing captain Han Solo team together with the loveable robot duo R2-D2 and C-3PO to rescue the beautiful princess and restore peace and justice in the Empire. poster:https://image.tmdb.org/t/p/w500/6FfCtAuVAW8XJjZ7eWeLibRLWTw.jpg release_date:2.333664e+08 title:Star Wars]

3.2 高级搜索

除了基本的全文搜索外，MeiliSearch 还支持多种高级搜索功能，例如过滤、分页和高亮显示等。

3.2.1 过滤搜索

package main

import (
	"encoding/json"
	"fmt"
	"github.com/meilisearch/meilisearch-go"
	"log"
	"os"
)

func main() {
	// 创建 MeiliSearch 客户端实例
	client := meilisearch.NewClient(
		meilisearch.ClientConfig{
			Host:   "http://localhost:7700",
			APIKey: "3EX4QpUfpqX6XfOIks-qWg6tvpQxdWmr7CxHUN4GgaA", // 如果使用了API密钥
		},
	)

	// 更新过滤器（请求之后等待一段时间才生效）
	//_, err := client.Index("movies").UpdateFilterableAttributes(&[]string{
	//	"id",
	//	"title",
	//	"overview",
	//})
	//if err != nil {
	//	log.Fatalf("Error updating filterable attributes: %v", err)
	//}

	resp, err := client.Index("movies").Search("star", &meilisearch.SearchRequest{
		Filter: "id > 100 AND (NOT title = 'Star Trek: The Motion Picture')",
	})
	if err != nil {
		log.Fatalf("Error searching: %v", err)
	}

	// 输出搜索结果
	for _, movie := range resp.Hits {
		fmt.Printf("%+v\n", movie)
	}
	// map[genres:[Action Adventure Science Fiction Thriller] id:154 overview:It is the 23rd century. The Federation Starship U.S.S. Enterprise™ is on routine training maneuvers and Admiral James T.

Aided by his exiled band of genetic supermen, Khan (Ricardo Montalban) - brilliant renegade of 20th century Earth - has raided Space Station Regula One, stolen a top secret device called Project Genesis, wrested control of another Federation Starship and sets out in pursuit of the Enterprise, determined to let nothing stand in the way of his mission: kill Admiral Kirk... even if it means universal Armageddon. poster:https://image.tmdb.org/t/p/w500/uPyLsKl8Z0LOoxeaFXsY5MxhR5s.jpg release_date:3.919968e+08 title:Star Trek II: The Wrath of Khan]

	// ......
}

3.2.2 搜索排序

默认情况下，Meilisearch 重点根据结果的相关性对结果进行排序。您可以更改此排序行为，以便用户可以在搜索时决定他们想要首先看到的结果类型。

package main

import (
	"encoding/json"
	"fmt"
	"github.com/meilisearch/meilisearch-go"
	"log"
	"os"
)

func main() {
	// 创建 MeiliSearch 客户端实例
	client := meilisearch.NewClient(
		meilisearch.ClientConfig{
			Host:   "http://localhost:7700",
			APIKey: "3EX4QpUfpqX6XfOIks-qWg6tvpQxdWmr7CxHUN4GgaA", // 如果使用了API密钥
		},
	)

	// 更新排序过滤器（请求之后等待一段时间才生效）
	//_, err := client.Index("movies").UpdateSortableAttributes(&[]string{
	//	"id",
	//})
	//if err != nil {
	//	log.Fatalf("Error updating filterable attributes: %v", err)
	//}

	resp, err := client.Index("movies").Search("", &meilisearch.SearchRequest{
		Sort: []string{
			"id:desc",
		},
	})
	if err != nil {
		log.Fatalf("Error searching: %v", err)
	}

	// 输出搜索结果
	for _, movie := range resp.Hits {
		fmt.Printf("%+v\n", movie)
	}
	// map[genres:[Crime Drama Thriller] id:460071 overview:Massachusetts, 1892.

}

3.2.3 多重搜索

允许您通过将一个或多个索引捆绑到单个 HTTP 请求中来执行多个搜索查询。多重搜索也称为联合搜索。

func main() {
	// 创建 MeiliSearch 客户端实例
	client := meilisearch.NewClient(
		meilisearch.ClientConfig{
			Host:   "http://localhost:7700",
			APIKey: "3EX4QpUfpqX6XfOIks-qWg6tvpQxdWmr7CxHUN4GgaA", // 如果使用了API密钥
		},
	)

	// 多重搜索文档
	resp, err := client.MultiSearch(&meilisearch.MultiSearchRequest{
		Queries: []*meilisearch.SearchRequest{
			{
				IndexUID: "movies",
				Query:    "star",
				Limit:    2,
				Offset:   0,
			},
			{
				IndexUID: "movies",
				Query:    "\"the Fifth Element\"",
				Limit:    2,
				Offset:   0,

	// 创建 MeiliSearch 客户端实例
	client := meilisearch.NewClient(
		meilisearch.ClientConfig{
			Host:   "http://localhost:7700",
			APIKey: "3EX4QpUfpqX6XfOIks-qWg6tvpQxdWmr7CxHUN4GgaA", // 如果使用了API密钥
		},
	)

	// 搜索相似文档
	resp := new(meilisearch.SimilarDocumentResult)
	err := client.Index("movies").SearchSimilarDocuments(&meilisearch.SimilarDocumentQuery{
		Id: "18",
