搜索引擎成果页面（Searchengineresultspage，SERP）（搜索引擎结果）

　SearchEngineResuitsPage的缩写，意思是查找引擎成果页面，用户输入要害词后，点击查找按钮后，查找引擎回来显现的成果页面。

　　SERP是为特定查找显现的列表或成果，SERP有时分界说为查找引擎成果的安排（placement），依据本系列的意图，我将其称为页面而不是安排，在SEO领域中，在SERP中取得杰出的表现就是全部。

C#编写了一个基于Lucene.Net的搜索引擎查询通用工具类：SearchEngineUtil

　　最近由于工作原因，一直忙于公司的各种项目（大部份都是基于spring cloud的微服务项目），故有一段时间没有与大家分享总结最近的技术研究成果的，其实最近我一直在不断的深入研究学习Spring、Spring Boot、Spring Cloud的各种框架原理，同时也随时关注着.NET CORE的发展情况及最新技术点，也在极客时间上订阅相关的专栏，只要下班有空我都会去认真阅读观看，纸质书箱也买了一些，总之近一年都是在通过：微信技术公众号（.NET、JAVA、算法、前端等技术方向）、极客时间、技术书箱不断的吸取、借鉴他人之精华，从而不断的充实提高自己的技术水平，所谓：学如逆水行舟，不进则退，工作中学习，学习后工作中运用，当然写文章分享是一种总结，同时也是“温故而知新”的最佳应用。

　　前面废话说得有点多了，就直奔本文的主题内容，编写一个基于Lucene.Net的搜索引擎查询通用工具类：SearchEngineUtil，Lucene是什么，见百度百科 ,重点是:Lucene是一个全文检索引擎的架构，提供了完整的查询引擎和索引引擎，Lucene.NET是C#及.NET运行时下的另一种语言的实现，官网地址：http://lucenenet.apache.org/ ，具体用法就不多说了，官网以及网上都有很多，但由于Lucene.Net的原生SDK中的API比较复杂，用起来不太方便，故我进行了适当的封装，把常用的增、删、改、查（分页查）在保证灵活度的情况下进行了封装，使得操作Lucene.Net变得相对简单一些，代码本身也不复杂，贴出完整的SearchEngineUtil代码如下：

　里面除了使用了Lucene.Net nuget包，还单独引用了PanGu分词器及其相关组件，因为大多数情况下我们的内容会包含中文。如上代码就不再细讲了，注释得比较清楚了。下面贴出一些实际的用法：

创建索引：

SearchEngineUtil.AddIndex(GetSearchIndexDir(), post, (doc, data) => BuildPostSearchDocument(data, doc));


        private Document BuildPostSearchDocument(Post post, Document doc = null)
        {

            if (doc == null)
            {
                doc = new Document();//创建Document
            }

            doc.Add(new Field("Id", post.Id.ToString(), Field.Store.YES, Field.Index.NOT_ANALYZED));
            doc.Add(new Field("Title", post.Title, Field.Store.YES, Field.Index.ANALYZED));
            doc.Add(new Field("Summary", post.Summary, Field.Store.YES, Field.Index.ANALYZED));
            doc.Add(new Field("CreateTime", post.CreateTime.ToString("yyyy/MM/dd HH:mm"), Field.Store.YES, Field.Index.NO));
            doc.Add(new Field("Author", post.IsOriginal ? (post.Creator ?? userQueryService.FindByName(post.CreateBy)).NickName : post.SourceBy, Field.Store.YES, Field.Index.NO));

            return doc;
        }

　删除索引：

SearchEngineUtil.DeleteIndex(GetSearchIndexDir(), "Id", post.Id);

　更新索引：

SearchEngineUtil.UpdateIndex(GetSearchIndexDir(), "Id", post.Id, BuildPostSearchDocument(post));

　分页查询：

var keyword = SearchEngineUtil.GetKeyWordsSplitBySpace("梦在旅途 中国梦");
                var searchResult = SearchEngineUtil.SearchIndexByPage(indexDir, (bQuery) =>
                {
                    var query = SearchEngineUtil.CreatePanGuMultiFieldQuery(keyword, false, "Title", "Summary");
                    bQuery.Add(query, Occur.SHOULD);
                    return new Dictionary<string, string> {
                    { "Title",keyword},{"Summary",keyword}
                    };
                }, () =>
                {
                    return new[] { new SortField("Id", SortField.INT, true) };
                }, doc =>
                {
                    return new PostSearchInfoDto
                    {
                        Id = doc.Get("Id"),
                        Title = doc.Get("Title"),
                        Summary = doc.Get("Summary"),
                        Author = doc.Get("Author"),
                        CreateTime = doc.Get("CreateTime")
                    };

                }, pageSize, pageNo, out totalCount);

其它的还有：判断索引中的指定文档记录存不存在、查询符合条件的索引文档等在此没有列出，大家有兴趣的可以COPY到自己的项目中测试一下。

这里可以看一下我在自己的项目中(个人全新改版的自己博客，还在开发中)应用搜索场景的效果：

最后说明的是：Lucene并不是一个完整的全文检索引擎，但了解它对于学习elasticsearch、solr还是有一定的帮助，目前一般应用于实际的生产项目中，多半是使用更高层的elasticsearch、solr。

(本文中的代码我是今年很早前就写好了，只是今天才分享出来)

我喜欢对一些常用的组件进行封装，比如过往封装有：

基于MongoDb官方C#驱动封装MongoDbCsharpHelper类（CRUD类）

基于RabbitMQ.Client组件实现RabbitMQ可复用的 ConnectionPool（连接池）
