Office 365 (SharePoint 2013 Online) - Missing results in Search Results webpart

Scenario: While building a search based application in Office 365 (SharePoint 2013 Online) , I observed a behavior which I thought was quirky. A page on a publishing site had a Search Results web part and a Content by Search web part. While configuring them, I set them to have the same query and result source.

Expected result would’ve been the exact same result set and count. But for some reason, the Content By Search web part was returning all the pages as expected but the search results web part was only returning a subset of it. What was even quirkier was that the search preview on the search results web part would display all the results.

I initially thought that some pages might not have been published and hence search results web part would not display them, but that was not the case. I started to debug what was being returned to the browser. I looked at the objects that the search results returned and did not find anything there. Starting to analyze the data, I realized all the pages that were not showing up had some content that was similar, even though they were unique pages the content had a similar tone to it. I think in the earlier versions of the Search Result Web Parts, the user had an option to “Trim Duplicates” which is no longer present in the SharePoint 2013 Search Result Web Part’s properties.

Digging a bit deeper, I found a way to set the Trim Duplicates to false.

1. Export the Search Results Web Part from your page.

2. Open the .webpart file in your favorite editor.

3. Search for “Trim Duplicates”

4. Set the Trim Duplicates property to False.

5. Upload the web part.

6. Add the web part to your page.

Change SharePoint 2013 Online (Office 365) to use your local time zone

If you upload your documents only to find that your Modified time stamp is hours off, your SharePoint Online site may be using the wrong Regional Setting for your Time Zone. This is generally set to Pacific Time (US and Canada) by default. Here are the steps to correct it:

1. In your team site, click Site Actions.

2. Click Site Settings.

3. On the Site Settings page, under the Site Administration section, click Regional settings.

4. In the Time Zone section set the Time zone drop-down list to the appropriate zone for you.

5. Click OK.

SharePoint Page Layout Error: Only Content controls are allowed directly in a content page that contains Content controls

The cause is improper case for the control tags in my page layout.  A few contorls used a lower case "c" instead of an uppercase "C" in the word content.  The page layout that had trouble had tags that looked like: instead of .  The specific offending tag is the one associated with the page title (<asp:Content ContentPlaceholderID="PlaceHolderPageTitle"runat="server">).  The solution was as simple as correcting the case of the tag name and all worked well.
