Properties and attributes

You can use several attributes to change the behavior of the component. The required attributes are query-string and entity-types.

Attribute	Property	Description
query-string	queryString	The query to send to Microsoft Search.
entity-types	entityTypes	One or more types of resources expected in the response. Possible values are: list, site, listItem, message, event, drive, driveItem, person, externalItem, acronym, bookmark, chatMessage. Default is `driveItem`, `listItem`, `site`.
content-sources	contentSources	Content sources to use with external items.
paging-max	pagingMax	The maximum number of pages to be clickable in the paging control. Default is `7`.
query-template	queryTemplate	Query template to use in complex search scenarios. Query templates are currently supported only on the beta endpoint.
fetch-thumbnail	fetchThumbnail	Sets whether the result thumbnail should be fetched from the Microsoft Graph. Default is `false`.
enable-top-results	enableTopResults	This triggers hybrid sort for messages: the first three messages are the most relevant. This property is only applicable to `entityType=message`. Default is `false`.
scopes	scopes	Optional array of strings if using the property or a comma delimited scope if using the attribute. The component uses these scopes (with a supported provider) to ensure that the user consents to the right permission.
size	size	The size of the page to be retrieved. The maximum value is `1000`. Default is `10`.
fields	fields	Contains the fields to be returned for each resource.
version	version	Optional API version to use when making the request. Default is `v1.0`.
cache-enabled	cacheEnabled	Optional Boolean. When set, it indicates that the response from the resource is cached. Override if `refresh()` is called or if `pollingRate` is in use. Default is `false`.
cache-invalidation-period	cacheInvalidationPeriod	Optional number of milliseconds. When set in combination with `cacheEnabled`, the delay before the cache reaches its invalidation period is modified by this value. Default is `30000` and uses the default invalidation period.
N/A	error	Read-only error from Microsoft Graph if request wasn't successful.

CSS custom properties

The mgt-search-results component defines the following CSS custom properties.

<mgt-search-results
  class="search-results"
  query-string="contoso"
  entity-types="driveItem"
></mgt-search-results>

.search-results {
  --answer-border-radius: 10px;
  --answer-box-shadow: 0px 2px 30px pink;
  --answer-border: dotted 2px white;
  --answer-padding: 8px 0px;
}

Methods

Method	Description
refresh(force?: boolean)	Call the method to refresh the data. By default, the UI only updates if the data changes. Pass `true` to force the component to update.

Events

Event	When is it emitted	Custom data	Cancelable	Bubbles	Works with custom template
`dataChange`	Fired after the component loaded its data.	`{ response: any, error: any }`. The `response` property contains the response retrieved from Microsoft Graph. The `error` property contains information about the error if one occurred.	No	No	Yes

For more information about handling events, see events.

Templates

The mgt-search-results component supports several templates that you can use to define the look and feel. To specify a template, include a <template> element inside a component and set the data-type to one of the following values.

Data type	Data context	Description
default	The response from Microsoft Graph.	The default can be used to render the entire response coming from Microsoft Graph.
result-*	Data item from the returned `value` array	Use the `result-` template instead of the `default` template when expecting the response from the graph to contain an array of items. The `result-` template is automatically repeated for each item returned by the resource. The `result-` template starts rendering the items as soon as they're ready (unlike the default template). You can have multiple `result-` templates, one per `entityType` (See the available `entity-type` in properties and attributes)
error	The error from Microsoft Graph.	This template is used if there's an error making the request.
loading	N/A	This template is used while the request is being made.
no-data	N/A	This template is used when the request returned no data.

Microsoft Graph permissions

Permissions required by this component depend on the data that you want to retrieve with it from Microsoft Graph. For more information about permissions, see Use the Microsoft Search API to query data.

Subcomponents

The mgt-search-results component consists of one or more subcomponents that might require other permissions than the ones required for this component. For more information, see the documentation for each subcomponent:

Authentication

The control uses the global authentication provider described in the authentication documentation to fetch the required data.

Cache

To enable and configure the cache, use the cacheEnabled and cacheInvalidationPeriod properties. By default, the mgt-search-results component doesn't cache any responses.

Object store	Cached data	Remarks
`response`	Complete response retrieved from Microsoft Graph for the query executed by `mgt-search-results`

For more information, see Caching.

Localization

The control exposes the following variables that can be localized. For details about how to set up localization, see Localizing components.

modified	`modified on`
back	`Back`
next	`Next`
