Description: 分享一段asp站内类似百度引擎的模糊搜索代码
早在N年前就有网友问过：类似百度的站内模糊搜索怎样才能实现？最近工作需要，做了一个 asp 站内搜索。要求完全匹配的关键词要排在前面，关键词要模糊匹配。在网上搜了半天没有找到需要的代码，只好自己编写，现在分享给有需要的人。
功能介绍：
1、利用分词技术，先把关键词拆分为多个词组。如：“搜索炼药师”，拆分为：“搜索”、“索炼”、“炼药”、“药师”等多个词组。
2、如：数据库标题字段完全匹配“搜索炼药师”的排在前面，数据库标题字段模糊匹配“搜索”、“索炼”、“炼药”、“药师”等多个词组的分别在后面展示。
3、如：数据库内容字段完全匹配“搜索炼药师”的展示出来也排在后面。-Share some asp station fuzzy search engines like Baidu code N years ago, there are users as early as asked: Similar to Baidu' s station fuzzy search How can we achieve? Recent work requirements, do a search for asp station. Requires an exact match to the top surface of keywords, keyword to fuzzy matching. Search the web for a long time did not find the necessary code, had to write your own, and now share with people in need. Features: 1, the use of word segmentation, first split into multiple keyword phrases. Such as: " Search refining pharmacists" , split into: " Search" , " cable refining" , " mixing drugs" , " pharmacist" and other phrases. 2, such as: Database header field exactly matches " Search refining pharmacists," the top surface, the database header field fuzzy matches " Search" , " cable refining" , " mixing drugs" , " pharmacist" and other phrases were showing in the back . 3, such as: da Platform: |

通过选择一些特殊的边缘点作为试探点，加快了匹配度计算的效率，而且，很
好的避免了在部分遮挡情况下简单阈值判断方法的误判。最后，算法利用最小
