The NA28 editors use the symbol 𝔊 to indicate a reference to the LXX. I am trying to use Logos to find all such instances, but the search I am running only picks up occurrences of 𝔊 in the material either at the beginning or end of the NA28. It is not picking up any of the times the symbol is used as a cross-reference (what I am actually searching for), such as Hebrews 1:6, for example. The screenshot below shows the results I get running a Basic search. If I use a Bible search for All Bible Text instead, I don't get any results at all. What am I doing wrong here? Thanks!
