Comment 4 for bug 893639

Thank you for your bug report, I didn't try with a chinese locale so it could be a cjk issue but the dash doesn't do substring matching, i.e it will not match "office" in "libreoffice", it does search in the name and description keys though (but only in the locale, not in english):

The libreoffice-startcenter has that comment string:
Comment[zh_CN]=兼容开放标准 ODF 的办公软件套装。由 The Document Foundation 支持。

I don't speak chinese but the glyphs seems different from the one you used

The libreoffice-writer.desktop uses:

Comment[zh_CN]=创建编辑文档、报告、信件和网页中的文本和图形。

Does any of those has the word you looked for?
