Can anyone confirm that normal behaviour is when a list is "hidden from browser" it removes it from the Search Crawl.. This is what is happening to me, is there a way to hide list but still have list to be part of search.
Have you tried Doing this :
Navigate to the site that contains the list or library that you want to change.
Locate and click the list or library you want to customize.
Click Site Actions, and then click Site Settings.
Under Site Administration, click Site Libraries and lists.
Click an item from the list, for example, Customize “Shared Documents.”
On the List Settings page, under General Settings, click Advanced settings.
In the Search section, under Allow items from this document library to appear in search results, select Yes to include all of the items in the list or library in search result or No to exclude all items from search results.
