How to index _geoloc in Magento?

To enable geo-searching, you must have geolocation data in your records stored in a _geoloc attribute that contains latitude and longitude (lat and lng properties). The coordinates must be numbers, not strings.

You can refer to the below code for indexing _geoloc using the algolia_after_create_product_object events. You can create attributes in Magento for latitude and longitude, and then retrieve the attribute values in the file:

    public function execute(Observer $observer)

    {

        $data = $observer->getData('custom_data');

        // update created_at MySQL date format to timestamp

        $geoLoca = array();

        $geoLoca['lat'] = 40.639751;

        $geoLoca['lng'] = -73.778925;

        // If a customer specifies latitude and longitude for each product using the 'lat' and 'lng' attributes, use below code

        // $geoLoca['lat'] = $productObject->getLat();

        // $geoLoca['lng'] = $productObject->getLng();

        $data->setData('_geoloc', $geoLoca);

    }
