This might make a great addition to the site, as there are over 20,000 maps, and trying to find a good map would take too long.

Community > Maps > Show all > Ctrl+F enter map name. Can use Ctrl+G to quickly get to the next result. Note that this is a browser feature.

Alternatively, you could use Muli’s Userscript (https://www.warzone.com/Forum/106092-mulis-userscript-tidy-up-dashboard), head to the maps page then click Search Maps.
