search center filter by content type

Question

In the current site we have a search center, but we would need to customize it to be able to filter by content type before the user types the search.

Thanks

This is possible with Advanced Search. You can follow the guide at http://waelmohamed.wordpress.com/2011/05/31/add-custom-search-properties-in-your-advanced-search-sharepoint-2010/ where it does exactly what you need. On step 6, when you add the mapping to the crawled property, just select "ows_ContentType" instead of "ReferenceNo" that the guide uses.
