Hi,
We use SharePoint 2013 Enterprise and have done for some time without issues.
We use a global search centre, search and "find a file" has been working fine forever!
Until last week, now find a file/item has stopped returning results for a single site collection.
Last week I created a new page in this SC and added 3 web parts search box/results/navigation. I specified that the results be displayed on the same page and I specified the default result source - the only change to this was to add a property filter to specify
the Url of the current site collection.
We wanted to have a search function in this site that only searched the contents of this site collection... and this works perfectly.
But somehow, since then, the find a file/item function returns nothing for all the lists and libraries in this site collection and I have no idea why!
Any body have any ideas as to the possible reason. I can't see how the 2 could be related.
