Our SharePoint environment is configured with SharePoint Search as the default search option and FAST Search as the secondary search option.
We have a bunch of host header site collections which are dependent on SharePoint Search and have a few new ones which need to work against FAST. One of our tenants (site collection) have developed custom webparts to work against the FAST service proxy directly.
Now for another new site collection, is there a way to switch the Search provider in the OOB webparts?
Upon doing some research, I have found the SearchResultsBaseWebPart.DefaultSearchProvider property which is read-only. Does anoyone know of a way to set this property (maybe via reflection) so that it can works against a non-default Search provider?
