I was curious how I can make a GET request of an account record based upon a "CustomField: “Value” instead of just a query value of as outlined below:

sales_account /api/search?q=hquery param]&include=sales_account

Currently the query param does not allow me to include two values, for example:

/“clientname”:”JohnSmith”, “zipcode”:”90210”]

Am I over looking something such as the filter function any help would be awesome?
