Craft Scout provides a simple solution for adding full-text search to your entries. Scout will automatically keep your search indices in sync with your entries.
This plugin requires Craft CMS 3.2 or later and PHP 7.1 or later.
Go to the Plugin Store in your project’s Control Panel and search for “Scout”. Then click on the “Install” button in its modal window.
The configuration has changed from how Scout v1 did its configuration. Please see the setup section below on how to configure Scout.
The following changes are the most notable:
- The
mappingsconfiguration key has been changed toindicesand there is a new way to configure the indices - The
criteriais now a callable that returns anElementQuery. Every Index should define asiteIdin the criteria, otherwise the primary site is chosen. - New
queueandbatchoptions added to the settings - Old confuguration keys on the mappings have been replaced by functions on the
rias\scout\ScoutIndexobject.
To define your indices, copy the scout.php file to your config folder.

* Scout listens to numerous Element events to keep them updated in

];The element type that this index contains, by default Scout uses craft\elements\Entry::class
Craft's default element type classes are:
craft\elements\Assetcraft\elements\Categorycraft\elements\Entrycraft\elements\GlobalSetcraft\elements\MatrixBlockcraft\elements\Tagcraft\elements\User
This function accepts an ElementQuery and should also return an ElementQuery
->criteria(function (ElementQuery $query) {
return $query->section('blog');
});The transformer that should be used to define the data that should be sent to Algolia for each element. If you don’t set this, the default transformer will be used, which includes all of the element’s direct attribute values, but no custom field values.
// Can be set to a function
->transformer(function(craft\elements\Entry $entry) {
return [
'title' => $entry->title,
'id' => $entry->id,
'url' => $entry->url,
];
}),
// Or a string/array that defines a Transformer class configuration
->transformer('MyTransformerClassName'),
// Or a Transformer class instance
->transformer(new MyTransformerClassName()),Your custom transformer class would look something like this:
<?php
use craft\elements\Entry;
use League\Fractal\TransformerAbstract;
class MyTransformerClassName extends TransformerAbstract
{
public function transform(Entry $entry)
{
return [
// ...
];
}
}For long documents it is advised to divide the element into multiple rows to keep each row within row data size. This can be done using splitElementsOn().
Make sure to return an array in your transformer for these keys.
->splitElementsOn([
'summary',
'matrixElement'
])Important -
distinctID(available after indexing) must be set up as an attribute for faceting for deletion of objects to work when using splitElementsOn.
You can use this to define index settings that get synced when you call the ./craft scout/settings/update console command.
This way you can keep your index settings in source control.
The IndexSettings object provides autocompletion for all Algolia's settings
->indexSettings(
\rias\scout\IndexSettings::create()
->minWordSizefor1Typo(4)
)You can access the Algolia settings set in your config file through the following Twig variables.
{{ craft.scout.pluginName }}
{{ craft.scout.algoliaApplicationId }}
{{ craft.scout.algoliaAdminApiKey }}
{{ craft.scout.algoliaSearchApiKey }}Scout provides two easy console commands for managing your indices.
To import one or all indices you can run the following console command
./craft scout/index/import <indexName?>
The indexName argument is not required, all your mappings will be imported when you omit it.
Clearing an index is as easy as running a command in your console.
./craft scout/index/flush <indexName?>
As with the import command, indexName is not required.
When flushing, Scout will ask you to confirm that you really want to clear all the data in your index. You can bypass the confirmation by appending a --force flag.
Does a flush/clear first and then imports the index again.
./craft scout/index/refresh <indexName?>
You can omit an element from being indexed by returning an empty array from the transform method:
ScoutIndex::create()
->transform(function (Entry $entry) {
// Check if entry is valid for indexing
$isValid = yourCustomValidation($entry);
// If entry fails validation, return empty array
if (! $isValid) {
return [];
}
// Return normal data attributes
return [
'name' => $entry->title,
...
'lorem' => $entry->lorem,
'ipsum' => $entry->ipsum,
];
});This event allows you to customize which elements or element types get checked on save (or more specifically, every time the SearchableBehaviour is triggered).
use rias\scout\behaviors\SearchableBehavior;
use rias\scout\events\ShouldBeSearchableEvent;
Event::on(
SearchableBehavior::class,
SearchableBehavior::EVENT_SHOULD_BE_SEARCHABLE,
function (ShouldBeSearchableEvent $event) {
$event->shouldBeSearchable = false;
});The event has a properties:
- $element (the element being saved)
- $shouldBeSearchable (wether or not the element should be searchable, defaults to
true)
An example use-case for this would be to check the type of the element that's beind saved and settings shouldBeSearchable to false when it's a Matrix block.
