Create complex filters with multiple properties

[bgaillard]

The purpose of this case is to implement complex filters based on multiple properties. This could be provided with a special filter URL query parameter in a Web Service for example.

GET /products?enabled=true&filter=price:<90-validity:>=3

This will retrieve products havin a price lower than 80 OR a validity greater or equals to 3.

The : in an equals operator and prevents conflicts with the = operator used in the URL query parameters.

A sample call using the Gomoob Data Mapper / Service Layer standard conventions would be for example.

$this->productService->fetch(
    $offset,
    $pageSize,
    [
        'enabled' => true,
        0 => 'price:<90-validity:>=3'
    ]
);

Please note that we use integer key to differentiate simple property filters from complex property filters.
