Minimal Path to Awesome

• Clone this repository

SPFx

• Go to the spfx directory
• In the command line run:
  • npm install
  • gulp serve

Azure Function (Not mandatory)

• Go to the functions directory
• Follow the README.md file instructions
• Set the correct service URL in the Search Box Web Part

Web Parts Configuration

Search Box Web Part

Default Search Query Settings

Setting	Description
Use a dynamic data source	You can set a default query text coming from am other data source. This case is particularly useful when you want to put a search box Web Part on the front page redirecting to an other page with the same query. Use the query string parameter 'q' from the builtin 'Page Environment' data source.

Search box options

Setting	Description
Enable query suggestions	The search box supports query suggestions from SharePoint. Refer to the following article to know how to add query suggestions in your SharePoint tenant (caution: it can take up to 24h for changes to take effect).
Send the query to a new page	Sends the search query text to a new page. On that page, use an other searh box Web Part configured with a dynamic data source as the default query. This Web Part uses the 'q' query string parameter.

Search query enhancement

Setting

Description

Use Natural Language Processing service

Turn this option 'on' if you want to enhance the query text with NLP services like LUIS. In the 'Service Url' field, enter the URL of the Azure Function endpoint. Refer the instructions in the '/functions/README.md' file to set up the service. In this sample, only relevant detected keywords are returned as q new query using LUIS. Enabling debug mode will show you relevant information about the entered query.

Search Results Web Part

Search Query Configuration

Setting	Description
Search query keywords	Here you choose to use a static search query or a query coming from a data source. It is recommended to use the associated Web Part coming with this sample. The search query is in KQL format so you can use search query variables (See this post to know which ones are allowed). You can only plug one source to this Web Part.

Search Settings

Setting	Description
Query template	The search query template in KQL format. You can use search variables here (like Path:{Site}).
Result Source Identifier	The GUID of a SharePoint result source.
Initial sort order	The initial search results sort order. You can use mutliple properties here.
Sortable fields	The search managed properties to use for sorting. Make sure these are sortable. With SharePoint Online, you have to reuse the default ones to do so (RefinableStringXX etc.). The order is the same as they will appear in the sort panel. You can also provide your own custom labels using the following format RefinableString01:"You custom filter label",RefinableString02:"You custom filter label",... If no sortable fields are provided, the 'Sort' button will not be visible.
Enable Query Rules	Enable the query rules if applies. Turn this options 'on' to display your SharePoint Promoted results (links only).
Selected properties	The search managed properties to retrieve. You can use these properties then in your Handlebar template with the syntax (item.property_name).
Refiners	The search managed properties to use as refiners. Make sure these are refinable. With SharePoint Online, you have to reuse the default ones to do so (RefinableStringXX etc.). The order is the same as they will appear in the refnement panel. You can also provide your own custom labels using the following format RefinableString01:"You custom filter label",RefinableString02:"You custom filter label",... This Web Part supports dynamic translation of taxonomy based refiners with few additional configurations (see below).
Number of items to retrieve per page	Quite explicit. The paging behavior is done directly by the search API (See the SearchDataProvider.ts file), not by the code on post-render.

Miscellaneous: Taxonomy values dynamic translation

This Web Part supports the translation for taxonomy based filters according to current site language. To get it work, you must map a new refinable managed property associated with ows_taxId_<your_column_name> crawled property.

Styling Options

Setting	Description
Web Part Title	Shows a title for this Web Part. Set blank if you don't want a title.
Show blank if no result	Shows nothing if there is no result
Show result count	Shows the result count and entered keywords
Show paging	Indicates whether or not the component should show the paging control at the bottom.
Result Layouts options	Choose the template to use to display search results. Some layouts are defined by default (List oand Tiles) but you can create your own either by clinkg on the "Custom" tile, or "Edit template" from an existing chosen template. In custom mode, you can set an external template. It has to be in the same SharePoint tenant. Behind the scenes, the Office UI Fabric core CSS components are used in a isolated way.
Handlebars Helpers	Load handlebar helpers to use in your template. Disable this option will make Web Part loading faster if you don't need them.

Templates with Handlebars

This Web Part allows you change customize the way you display your search results. The templating feature comes directly from the original react-content-query-webpart so thanks to @spplante!

Query variables

The following out of the box query variables are supported/tested:

• {searchTerms}
• {Site}
• {SiteCollection}
• {URLToken}
• {User}
• {Today}
• {SearchBoxQuery}
• {CurrentDisplayLanguage}
• {CurrentDisplayLCID}

The following custom query variables are supported:

• {Page.<column>} - where column is the internal name of the column.
  • When used with taxonomy columns, use {Page.Column.Label} or {Page.Column.TermID}
• {CurrentYear} - Todays's date four digits, 2018
• {CurrentMonth} - Today's month, 1-12
• {CurrentDate} - Today's date, 1-31
  • Sample query template: {searchTerms} Write>2010-{CurrentMonth}-{CurrentDate}

Best bets

This WP supports SharePoint best bets via SharePoint query rules:

Elements previews

Previews are available, only for the list view, for Office documents and Office 365 videos (not Microsoft Stream). The embed URL is directly taken from the ServerRedirectedEmbedURL managed property retrieved from the search results.

The WebPart must have the following selected properties in the configuration to get the preview feature work (they are set by default):

• ServerRedirectedPreviewURL
• ServerRedirectedURL
• contentclass
• ServerRedirectedEmbedURL
• DefaultEncodingURL

This preview is displayed as an iframe when the user clicks on the corresponding preview image. DOM manipulations occur to add the iframe container dynamically aside with the container.

Features

This Web Part illustrates the following concepts on top of the SharePoint Framework:

• Build an user friendly search experience on the top of the SharePoint search REST API with paging, refiners and query suggestions using the @pnp JavaScript library.
• Use Handlebars to create templates for search results according to your requirements like the good old display templates.
• Using the SPFx dynamic data feature to connect Web Parts and/or Extensions.
• Using SharePoint taxonomy using JSOM in SPFx (filter translations)
• Integrate the @pnp/spfx-property-controls in your solution (PlaceHolder control).
• Integrate multiple Office UI Fabric components (DocumentCard, Panel, GroupedList, ...) to fit with the native Office 365 theme.
• Use the React container component approach inspiring by the react-todo-basic sample.
• Use on-el-resize by Andrew Koltyakov to resize iframes dynamically
