Net Core使用Lucene.Net和盘古分词器实现全文检索

阅读更多关于 Net Core使用Lucene.Net和盘古分词器实现全文检索

Lucene.net Lucene.net是Lucene的.net移植版本，是一个开源的全文检索引擎开发包，即它不是一个完整的全文检索引擎，而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，是一个高性能、可伸缩的文本搜索引擎库。它的功能就是负责将文本数据按照某种分词算法进行切词，分词后的结果存储在索引库中，从索引库检索数据的速度非常快。Lucene.net需要有索引库，并且只能进行站内搜索。（来自百度百科）效果图盘古分词如何使用将PanGu.dIl与PanGu.Lucenet.Analyzer. dl并加入到项目中将Dict文件，拷贝到项目Bin文件夹里面字典文件夹下载： https://pan.baidu.com/s/1HNiLp6bCcodN8vqlck066g 提取码: xydc 测试可以看到，盘古分词相对Lucene.net自带的一元分词来说，是比较好的，因为一元分词不适合进行中文检索。一元分词是按字拆分的，比如上面一句话，使用一元分词拆分的结果是："有","一","种","方","言","叫","做","不","老","盖","儿"。如果查找“方言”这个词，是找不到查询结果的。不符合我们的检索习惯，所以基本不使用。拓展上面的"不老盖儿"（河南方言），这里想组成一个词，那么需要创建"不老盖儿"词组并添加到字典里面。使用DictManage工具

Find all files in directory with string or pattern in filename with PHP

阅读更多关于 Find all files in directory with string or pattern in filename with PHP

问题 I'm trying to list out files in a directory (recursive or non) with PHP where filename matches a certain pattern. I've never been too great with regex so any help you could offer would be great. I could search for a literal check on the filenames returned, but I think that's not such a great idea :) Update + Final Solution: 1/18/2011 @ 8:06 PM I found another way to do what I was looking for once I understood regex a bit more. Granted I was entirely frustrated about where I was with regex, I

问题 Using C# (.NET), how can I search a file system given a directory search mask like this: (?) \\server\Scanner\images\*Images\*\*_* For example, I need to first find all top-level directories: \\server\Scanner\images\Job1Images \\server\Scanner\images\Job2Images ...then I need to procede further with the search mask: \\server\Scanner\images\Job1Images\*\*_* \\server\Scanner\images\Job2Images\*\*_* This doesn't seem too complicated but I can't figure it out for the life of me...
