In google Chrome, when you have visited a site, say wikipedia.com, your can thereafter search the site directly from the omnibar by typing in a few letters then hitting tab. However, I noticed that after I clear my cache, Chrome does not remember the search autofills, and I once again have to visit the site manually for it to take effect.

Is there a way to make the omnibar searches permanent even after doing a full cache clear in google Chrome? Thanks.

Update: I tried the suggestion below, but bookmarking the site just allowed me to autocomplete the address. It did not allow me the option to hit tab to do the search directly in the omnibar. Any suggestions?
