I'm new to SharePoint and FAST.
In SharePoint 2007 implementation for our projects we used "Esp-Searchapi" for querying the back-end FAST ESP 5.3.
As we are now migrating to SharePoint 2010 and FAST Search for SharePoint (FS4S), I'll be creating WebParts or use existing one, but the existing API code will no longer work.
I need some references which will provide me a good jump start for querying FS4S back-end search and get the search results.
Thanks.
