I get search results based on the search like http://crowdedgallery.co.uk/catalogsearch/result/index/?&q=cats
And I want to refine it more by adding another attribute to the search by http://crowdedgallery.co.uk/catalogsearch/result/index/?orientation=landscape&p=3&q=cats
Where I have the values of the attribute "Orientation" as "Landscape" and "Portrait",
I know it is possible to filter using the Search in Layered Navigation, but I just want to FILTER the Search Results after the output with "Orientation"
Is it possible to change something in the Query.php or any other methods,
please help,
I am new to magento and am stuck,
