I have successfully consumed a published SharePoint 2013 Search Service Application in my 2010 Farm. However my 2010 Search Scope no longer works... and you can't create Search Scopes in 2013.
So, how do I configure my 2013 farm to mimic the search scope? I'm not sure if this would be a Result Source or a Query Rule... I've used the same name for both and it still doesn't work, so I'm now trying a full crawl.
Update for Matt:
My 2010 scope is very simple scope:
- "ABC Guide". Rules:
Folder = http://server/business/guide [Include].
- ContentSource = ABC Portal [Require].
My 2010 search results web part is here:
As I say, in 2013, I have an "ABC Guide" result source (and Query Rule for testing):
- Query Transform: {searchTerms} path:"http://server/business/guide"
Interestingly, the People Search Core Results Web Part (which works in 2010-->2013)doesn't define a Scope in its "Location Properties". Somehow it must apply its filtering another way?
The actual error I get is: "Scope in your query does not exist".
