How to search a custom field in Sharepoint Foundation 2010

Question

I'm trying to make the search server to look inside fields that are not in custom definition. For example i've a document library and i had the column MyCol... If i search and put in the query string MyCol:Value this cannot find the results even if Value is exactly the content of the column..

I tried also to create a Custom Column at Site Collection level and then add the colum from this "template"...

What i'm doing wrong? Does Search Server admit custom fields in Foundation like in Enterprise version of sharepoint?

Thank you very much!

When you crawl a custom field tyou get a crawled property. To be able to search for values in the custom field you have to map the crawled property to a new or existing managed property.
