Custom Content Filtering Issue

Hi,

Not sure if i am missing something obvious here but i'm trying to filter some content to allow users to search through some factsheets that have a 'description' and 'keywords' field for each entry.

The options i'm passing to perch_content_custom are:

Array
(
    [template] => factsheet.html
    [page] => /factsheets-list.php
    [filter] => Array
        (
            [0] => Array
                (
                    [filter] => live
                    [match] => eq
                    [value] => live
                )

            [1] => Array
                (
                    [filter] => description
                    [match] => contains
                    [value] => test
                )

            [2] => Array
                (
                    [filter] => keywords
                    [match] => contains
                    [value] => test
                )

            [match] => or
        )

    [skip-template] => 1
    [return-html] => 1
)

The debug output i get when running this is:
