riotsearch 介绍
riot 分布式全文搜索引擎, 采用 Go 语言开发。功能特性：
-
支持计算关键词在文本中的紧邻距离（token proximity）
-
支持计算BM25相关度
-
支持多种持久存储
-
支持 heartbeat
-
可实现分布式索引和搜索
-
采用对商业应用友好的Apache License v2发布
示例代码：
package main
import (
"log"
"github.com/go-ego/riot"
"github.com/go-ego/riot/types"
)
var (
// searcher is coroutine safe
searcher = riot.Engine{}
)
func main() {
// Init searcher
searcher.Init(types.EngineOpts{
Using: 4,
SegmenterDict: "./dict/dictionary.txt"})
defer searcher.Close()
text := "Google Is Experimenting With Virtual Reality Advertising"
text1 := `Google accidentally pushed Bluetooth update for Home
speaker early`
text2 := `Google is testing another Search results layout with
rounded cards, new colors, and the 4 mysterIoUs colored dots again`
// Add the document to the index, docId starts at 1
searcher.IndexDoc(1, types.DocIndexData{Content: text}, false)
searcher.IndexDoc(2, types.DocIndexData{Content: text1}, false)
searcher.IndexDoc(3, types.DocIndexData{Content: text2}, false)
// Wait for the index to refresh
searcher.FlushIndex()
// The search output format is found in the types.SearchResp structure
log.Print(searcher.Search(types.SearchReq{Text: "google testing"}))
}
主要改进:
