我知道在清除 apt-xapian-index 后您不能在 Synaptic 中使用快速过滤器，但是还有更严重的问题吗？
我知道有一些性能问题，当你有它时：
没有什么严重的。您可能会失去一些功能（请参阅下面的说明），但如果您不需要它，则可以删除该软件包（请注意它不会卸载任何其他软件包）。如果您后来发现这是一个错误，您可以重新安装它。
Description: maintenance and search tools for a Xapian index of Debian packages
This package provides update-apt-xapian-index, a tool to maintan a Xapian
index of Debian package information in /var/lib/apt-xapian-index, and
axi-search, a command line search tool that uses the index.
.
axi-cache allows to search packages very quickly, and it also interfaces with
the shell command line completion in a smart way, providing context-sensitive
keyword and tag suggestions even before the search command is actually run.
.
update-apt-xapian-index allows plugins to be installed in
/usr/share/apt-xapian-index to index all sorts of extra information, such as
Debtags tags, popcon information, package ratings and anything else that would
fit.
.
The index generated by update-apt-xapian-index is self-documenting, as it
contains an autogenerated README file with information on the index layout and
all the data that can be found in it.
