Query on Hierarchical list applet

Hi,

I want to use hierarchical list applet but it seems query on hierarchical list applet is filtered by the query on master record. IE. : If master record doesn't correspond to criteria then list applet show no record.

By example on sample database, Applet Line Items on screen Quote is hierarchical. When I query on product present on subline but not on master record, result show no record (by example : Product like '*drive') even if subline exists. When I query on product existing on master line, record appear and sublines are filtered too.

I expect to have filter without consideration on parent product : If I query on product associated to subline, I need to have product without parent line.
