Ads searching by ads' ids
Is there a way to limit ads' search by ad's id only, so that a particular ad can be found only if the visitor enters a specific ad's id?
Searching would be based solely on ads' ids. So for example: an ad titled "Ferrari" with an id 53201 can be only searched and visible in search results when a visitor inputs exact same number (53201). If visitor enters 5320 there will be no search results. If visitor enters in the search bar "Ferrari" or any other letters/words available within ads' content, there will be no search results (searching may also be limited to numbers only, so that typing any letters would result in an error/notification/no search results page).
Any ideas?
