I have to fetch collections details by ajax call and also apply a filter on it.

So I have created a controller add-on, call it by ajax and put below code in it.

$collectionDataList=Entry::whereCollection('Store')->values()->all();

    foreach ($collectionDataList as $item) {
        echo '<pre>'; print_r($item->data()); exit;
    }

But I want to filter data by fields of the collection. So is there any where function or any other way?
