I just got a question from someone who wanted to know how to retrieve all the Office 365 Group documents he had access to. When you are having a lot of groups in your organization, files could be spread across them. Search is in most cases the answer to finding your documents easily.
Last year I did a couple of session about how to improve the search experience in your environment. In this session, I highlighted a couple of simple things that mostly stay untouched and things that can be quickly implemented. One of these key takeaways was implementing synonyms. Configuring synonyms can be done via the thesaurus functionality and works on-premises differently than on SharePoint Online.
Last week I finally found some time to get my demo tenant up and running with hybrid search configuration. The new hybrid search experience eliminates the need of the result block. All results are aggregated together right now. So that means if you do a search query, you could get SharePoint Online results and on-premises results.
If you created your own display templates, you most probably have used the AddPostRenderCallback function. The AddPostRenderCallback function allows you to execute code once the display template completed rendering and this function can be used in every template (control, item, …). Now when you are creating your own refiner display templates and want to do something once all the refiners are rendered, the first approach would be to create a AddPostRenderCallback function in the refinement control template.
This article explains a quick tip how you can allow empty search queries. This functionality is necessary when you have pages on which you configured the search web parts to use predefined queries in order to show results when the page gets loaded. Note: This could be either configured in the web part itself or via a result source.
