An item is not shown unless it is searched by the first word of its name

An item is not shown unless it is searched by the first word of its name.  For example say there are 5 packets of "Pedigree 1kg Adult Chicken and Rice" in inventory.  But if I type "1kg" or "Adult" or "Chicken" or "Rice" in the search, no item is shown.
