超查找引擎（metasearchengine）

超查找引擎是一种特殊类型的搜索引擎，它既可以搜索一个单一网站上的内容，也可以搜索多个网站上的素材。它以无休止把信息从不同网站整合在一起，并让用户以方便的方式进行使用。超查找引擎一般会把一个网站的内容分解成多个领域，然后将其搜索结果按照用户的关键字进行评分，从而确定最有价值的信息，从而大大缩短搜索时间。由于它可以将多个网站上的信息整合在一起，因此可以涵盖更广范围的信息，从而节约用户搜索资源。

相关性指的是事物之间的关联程度或相似程度。在信息检索中，相关性通常描述了查询与搜索结果之间的匹配程度或相关性程度。一般来说，相关性越高，搜索结果越符合查询的意图，而反之则越不相关。相关性的评估通常由算法和模型来实现，例如TF-IDF、BM25等算法。

网站降权

威海seo术语威海网站降权
1649

网站降权是指搜索引擎对一个网站在搜索结果中的排名降低。这可能是因为搜索引擎发现了一些对用户不友好或虚假的行为，如采用黑帽SEO技术、大量的垃圾链接或内容不合法等。当网站被降权后，其在搜索结果中的排名可能不如以前那么靠前，这会对网站的流量和收益产生负面影响。为了避免网站被降权，网站管理员应该遵循搜索引擎的规则和指南，及时优化网站内容和架构，避免使用不正当的优化手段。
