Keywords for plugins for better search in the future

I would like to have a free textfield area for plugins and be able to see that plugin when I search for a word that is in that tag/keywords of that plugin. 
Example: Let's say, there is a plugin called AAAZZZ, but that is really a delay plugin. I want to be able to put "delay" for that plugins keywords/tag/text fields so that next time I search for a 'delay' plugin, that AAAZZZ plugin shows up in the plugin browser window. 
 
Thanks in advance.
