SharePoint 2013 search result web part not showing all result

I add the standard search result web part to an empty page layout. I click "change query", and add the query I want. The search result preview shows 179 results. Perfect, just what I wanted. I click "OK", "Apply", and publish the page. Now it only shows 7 results. I haven't configured nothing else on the search result web part.

Where did the remaining 172 results go? Any suggestions are appreciated :)

I had the same issue, it turned out that Search Results web part was incorrectly trimming results that were considered duplicates.

I fixed this by setting TrimDuplicates to false. To do this:

• Export the web part,
• change TrimDuplicates to false in the DataProviderJSON property, and
• add the web part back to your page.

Hope that helps Christopher Scolt
