I've been exploring usage of relative image positions qualifiers using d:Property:P2677. The documentation in this page seems to suggest that I can search for images that have depicts statements (P180) with the relative image position qualifier (P2677) using a query like haswbstatement:P180=Q76|P2677=*, but that seems to capture both images with that qualifier and those without. Using something like haswbstatement:P180=Q76[P2677=*] doesn't seem to work either (no results are returned).
And actually, my main goal was to search for images with depict statements but without the qualifier. I tried a query like haswbstatement:P180=Q76 -haswbstatement:P180=Q76[P2677=*] but that (unsurprisingly, given the above) also doesn't return any results.
Is this a limitation of the extension, or am I using the syntax incorrectly?
