介绍Lucene.Net
一、Lucene.Net 来源：Lucene是Java开发的全文检索库；Lucene.Net是Lucene的.NET平台C#移植版，Apache基金会开源项目，遵循Apache License协议。 定位：不是成品搜索引擎，只是一套全文检索开发组件包，提供查询引擎、索引引擎，需要开发者自己编码实现检索功能；不会自动爬取内容，需要手动提取文本添加到索引。 开发简要步骤 初始化分词器Analyzer 打开IndexWriter索引写入器 逐个添加文档 关闭后，索引自动优化，变更生效 核心原理：索引文件 建立索引时，会生成独立的索引文件，把词语和文章文档做关联。 用户搜索时读取索引文件，不再直接查询数据库。 ✅优点：查询速度快，大幅降低数据库压力 、 缺点：搜索不是实时。新增文章不会立刻出现在搜索结果，需要手动/定时重建索引。 二、盘古分词 定位：中英文分词组件，支持自定义分词规则，常配合Lucene.Net使用。 作用：解决Lucene自带词库中文词汇不足的问题。举例：文章标题望向黑色迷墙 Lucene自带词库可以识别黑色，搜索“黑色”可以找到这篇文章； 自带词库没有迷墙，直接用Lucene分词时，搜“迷墙”无法匹配文章； 接入盘古分词，就可以识别迷墙这个词，建立索引，用户搜索迷墙就能检索到文章。 总结...
