全局搜索 未索引软件的关键词（Keywords）字段

补充 8/12 GenericName 字段也应被检索，它反映了应用程序的通用功能。例如 Rygel 的通用名是 UPnP/DLNA 服务。按规范所述，Name GenericName Keywords 三个字段互不重叠，都可用于提升搜索命中率。

FreeDesktop.org 桌面入口规范 第 1.1 版起引入了 Keywords 字段，可用于提高搜索命中率。

Keywords | A list of strings which may be used in addition to other metadata to describe this entry. This can be useful e.g. to facilitate searching through entries. The values are not meant for display, and should not be redundant with the values of Name or GenericName.

例如，以下为 eog.desktop 部分内容。

Name[zh_CN]=图像查看器
Keywords[zh_CN]=Picture;Slideshow;Graphics;图片;幻灯片;图像;
Keywords=Picture;Slideshow;Graphics;

那么当我搜索 slideshow 等词时，应该会有“图像查看器”的结果。

STEPS TO REPRODUCE | 复现步骤

1. sudo apt install eog
2. 可见启动器里新增了“图像查看器”图标
3. 搜索其关键词之一 —— graphics
