This method is not standardized like GET, POST, etc., but has become accepted in some APIs. It is used to send user query data to the server to filter the resource sought. It's more like an advanced GET request. It comes in handy in scenarios where the query parameters for GET become too complex or hard to manage. With SEARCH, you can send the query parameters in request body, making it more structured than a long list of parameters on the URL with the GET method. In many cases, it's considered better in terms of performance when dealing with complex queries or large datasets.
