+#### Modifying The Import Query
+
+If you would like to modify the query that is used to retrieve all of your models for batch importing, you may define a `makeAllSearchableUsing` method on your model. This is a great place to add any eager relationship loading that may be necessary before importing your models:
+
+    /**
+     * Modify the query used to retrieve models when making all of the models searchable.
+     *
+     * @param  \Illuminate\Database\Eloquent\Builder  $query
+     * @return \Illuminate\Database\Eloquent\Builder
+     */
+    protected function makeAllSearchableUsing($query)
+    {
+        return $query->with('author');
+    }
