Framework: Clearing Search Index

Earlier this month, Osm Framework started requiring 'limit()' on all search index queries, and the naive Osm Admin search indexer code that deletes all entries one by one doesn't do that:

// Osm\Admin\Schema\Indexer\Search::fullReindex()
foreach ($this->searchQuery()->ids() as $id) {
    $this->searchQuery()->delete($id);
}

It's time to create a deleteAll() method for this use case:

// Osm\Framework\Search\Query
public function deleteAll(): void {
    throw new NotImplemented($this);
}

// Osm\Framework\ElasticSearch\Query
public function deleteAll(): void {
    $request = $this->fireFunction('elastic:deleting_all', [
        'index' => "{$this->search->index_prefix}{$this->index_name}",
        'refresh' => $this->search->refresh,
        'body' => [
            'query' => [
                'match_all' => (object)[],
            ],
        ],
    ]);

    $this->search->client->deleteByQuery($request);

    $this->fire('elastic:deleted_all');
}

// Osm\Framework\AlgoliaSearch\Query
public function deleteAll(): void {
    $this->fire('algolia:deleting_all');

    $request = $this->search->initIndex($this->index_name)
        ->deleteBy(['filters' => 'id > 0']);

    if ($this->search->wait) {
        $request->wait();
    }

    $this->fire('algolia:deleted_all');
}

This method also gets called in the test suite.
