 广义的ukui-search除了包括全局搜索应用，还包括在ukui桌面环境中的本地搜索服务以及其开发接口。基于文建索引服务，应用搜索数据服务等基础数据源服务，可以提供基于C++接口的搜索功能，应用开发者可以通过引用动态库的形式直接使用其搜索功能。除此之外，ukui桌面环境搜索服务还提供了一组基于Qt插件框架的插件接口，用户可以通过继承接口以实现搜索功能的扩展。
 以下提到的ukui-search如无说明均指后者。

-xxx代表版本号。其中，ukui-search 为全局搜索应用本体，libukui-search包提供了搜索服务基本功能以及扩展接口，libukui-search-dev为其开发包。libchinese-segmentation包为搜索服务提供了NLP能力，如中文分词等。ukui-search-systemdbus包提供了一些systemdbus提权操作。
