Intertext search

I was working on a search and am not able to make it work. The example from the wiki perfectly fit my needs, but I'm missing something. 

From the Wiki on Search Help near the bottom in the Logos Now section:

Intertext

Intertext (Intertextuality) labels expose the data behind the interactive resource “New Testament Use of the Old Testament”.

• {Label Intertext WHERE [NOT] Source=~BibleReference1}
• {Label Intertext WHERE [NOT] Target=~BibleReference2}
• {Label Intertext WHERE [NOT] Relationship=~Citation | Quotation | Allusion | Echo}
• {Label Intertext WHERE [NOT] Corpus=~New Testament | ... |} —> not strictly needed as the only Corpus is the NT.

For example:
   {Label Intertext WHERE Source<Gen-Mal>} —> finds passages in the NT whose Source is the OT
   {Label Intertext WHERE Target<Mt-Rev>} —> finds passages in the OT that are used in the NT
   {Label Intertext WHERE Source<Gen-Deut> AND Relationship=Quotation} —> finds quotations in the NT that come from Gen-Deut.
   {Speaker <Person Jesus>} WITHIN {Label Intertext WHERE Source<Gen-Mal>} —> finds passages from the OT that were used by Jesus
   {Speaker <Person Moses>} WITHIN {Label Intertext WHERE Target<Mt-Jn>} —> finds OT passages spoken by Moses that were used in the Gospels
   {Speaker <Person Moses>} WITHIN {Label Intertext} —> finds Intertext passages in both OT & NT where the speaker is Moses

I am not able to achieve any results from these Intertext searches. 

Have you had success?
