Implement global search

This feature allows the user to globally search across a selected set of entities of your application.

Configuration

php

// In config/sharp.php
return [
   // ...
   'search' => [
      'enabled' => true,
      'placeholder' => 'Search for anything...',
      'engine' => \App\Sharp\MySearchEngine::class,
   ],
];

// In config/sharp.php
return [
   // ...
   'search' => [
      'enabled' => true,
      'placeholder' => 'Search for anything...',
      'engine' => \App\Sharp\MySearchEngine::class,
   ],
];

Write the class

The search engine class must extend Code16\Sharp\Search\SharpSearchEngine, which would imply to implement the searchFor(array $terms): void method; here’s an example:

php

class MySearchEngine extends SharpSearchEngine
{
    public function searchFor(array $terms): void
    {
        $resultSet = $this
            ->addResultSet(
                label: 'Posts',
                icon: 'fa-file-o',
            );

        $builder = Post::query();

        foreach ($terms as $term) {
            $builder->where('title', 'like', $term);
        }

        $builder
            ->limit(10)
            ->get()
            ->each(function (Post $post) use ($resultSet) {
                $resultSet->addResultLink(
                    link: LinkToShowPage::make('posts', $post->id),
                    label: $post->title,
                    detail: $post->author->name,
                );
            });
    }
}

class MySearchEngine extends SharpSearchEngine
{
    public function searchFor(array $terms): void
    {
        $resultSet = $this
            ->addResultSet(
                label: 'Posts',
                icon: 'fa-file-o',
            );

        $builder = Post::query();

        foreach ($terms as $term) {
            $builder->where('title', 'like', $term);
        }

        $builder
            ->limit(10)
            ->get()
            ->each(function (Post $post) use ($resultSet) {
                $resultSet->addResultLink(
                    link: LinkToShowPage::make('posts', $post->id),
                    label: $post->title,
                    detail: $post->author->name,
                );
            });
    }
}

This code manipulates Code16\Sharp\Search\SearchResultSet objects, which are used to group results by entity type (meaning: you may add several result sets). Here’s a list of methods exposed by this object:

addResultLink(SharpLinkTo $link, string $label, ?string $detail = null): ResultLink: add a result in the set, providing a SharpLinkTo object (see documentation).
hideWhenEmpty(bool $hideWhenEmpty = true): self: hide the result set if it’s empty (default is false).
setEmptyStateLabel(string $emptyStateLabel): self: override the default empty state label (not used if hideWhenEmpty() is true).
validateSearch(array $rules, array $messages = []): bool: handle validation, see below.

TIP

In the very likely case you need to query multiple models, write a separate method for each of them (searchForPosts($terms), searchForOrders($terms)...), and call them from the searchFor() method.

Validate search terms

You may need to validate whatever was typed by the user in the search field. Sharp allow to do so in each result set independently, for convenience:

php

class MySearchEngine extends SharpSearchEngine
{
    public function searchFor(array $terms): void
    {
        $resultSet = $this
            ->addResultSet(
                label: 'Posts',
                icon: 'fa-file-o',
            );
            
      if (! $resultSet->validateSearch(
          ['string', 'min:3'], 
          ['min' => 'Please type at least 3 characters']
      )) {
          // No need to query the DB
          return;
      }
            
      // Search terms are valid, proceed with query
      // ...
    }
}

class MySearchEngine extends SharpSearchEngine
{
    public function searchFor(array $terms): void
    {
        $resultSet = $this
            ->addResultSet(
                label: 'Posts',
                icon: 'fa-file-o',
            );
            
      if (! $resultSet->validateSearch(
          ['string', 'min:3'], 
          ['min' => 'Please type at least 3 characters']
      )) {
          // No need to query the DB
          return;
      }
            
      // Search terms are valid, proceed with query
      // ...
    }
}

As you can see in this example, the validateSearch() method accepts an array of regular Laravel validation rules, and an optional array of custom validation messages. Sharp will not display results if the validation fails, but a good practice is to return early in this case, to avoid unnecessary queries.

Use the search field

The search field is available in the top bar of Sharp, and can be called with these pretty standard keyboard shortcuts: Ctrl+K, Cmd+K (Mac) or simply /.
