Can't use two ore more filters

Hi @nagiyevel,

you have to nest your query differently as the term query does only support one term. See also the bool query docs.

In your example you need to do something along the lines of:

[filter] => Array(
    [bool] => Array(
        [must] => Array(
            [term] => Array(
                [fk_product_category] => 1
            ),
            [term] => Array(
                [fk_product_group] => 1
            )
        )
    )
) 

although I am not sure whether you need the Array also for the term query (maybe that's specific to your program language which I do not recognize from this example).
