Catalog Search Over Explicit Search

In commerce server, the catalog search has been known to be the most easiest and flexible way to pull out effective needy data from the catalog system. However, this may be not true in some cases. In a catalog search , we are not taking into consideration that by catalog search we allow the commerce to search for each and every product within the given condition. This consumes more of time and effort. So hence a explicit search is always preferred over the catalog search.
