Add support for with_lookup head_only

Browse source 
head_only mode cna be run with_lookup - but there is no L0 index created in this case.

So the L0 index wasn't returning a potition list and the L0 cache wasn't being checked.

Code now checks every  position in the L0 cache, when  a lookup is attempted in head_only mode.
