Multiline report kw

Content

Good afternoon,

"Value 'bonus' must be an integer. To allow keyword searching, change the filter type. The returned results do not include this term."

I have this problem whenever I do not have the p parameter in the URL and have a keyword (kw) on it, thing is I do not want the Multiline widgets to search for kw, now I went as far as defining the static_filter to empty, but that is not having any effect.
Are you guys aware if there is any way of refusing the kw as a filtering parameter without customizing the widget?
