使用 apt search 得到的结果很乱，有解决办法吗？

不管时apt search还是apt-cache search 在有时搜索一个软件时，会出来一堆没有关系的软件，这是为什么？
如：
vim（源中有这个软件包）
adapta(源中没有的包)
得到搜索结果都是乱七八糟一堆，请问这个能解决吗？

ps：还有一个小问题，请问这个网站使用的是什么网站程序？感觉比知乎好玩。

以 apt search adapta 为例

最后一个

xapian-tools/unstable,testing 1.4.3-2 amd64
  Basic tools for Xapian search engine library

然后 apt show xapian-tools | grep adapta

 The Xapian search engine library is a highly *adapta*ble toolkit which allows

所以搜到是因为 Description 里面包含 adapta

那如何精确查找某个包呢？只搜索包名，不管依赖和描述文件，不然这样查找感觉好累。

4

apt-cache search . | grep vim

虽然还是能搜到简短描述中的内容，但至少结果会简洁很多

只搜包名的话，这样？

apt-cache search . | awk '{print $1}' | grep vim

嗯嗯，这个命令正解，谢谢啦，突然发现debian 9 貌似自带ppa功能了，都不用添加了。还有论坛程序是Discourse，写给像我一样好奇的朋友，哈哈……
