Hi Heather,

I should maybe have specified that the situation I was describing did *not* use
UseControlNumber. If UseControlNumber is activated, the exact control number in
$w is searched in the control-number index, as you described in your use case.

When that syspref is deactivated, and you have values in 780/785 $a and/or $t
the values are searched in the title index (or they were in 2018 when I wrote
this bug report).

In the same link you provided
https://www.loc.gov/marc/bibliographic/bd760787.html under subfield $a it says
it's the main entry ("Main entry heading data (without the content designators)
from field 100 (Main Entry-Personal Name), 110 (Main Entry-Corporate Name), or
111 (Main Entry-Meeting Name) in the related record.") meaning it should
contain the author's name. 

My proposal was to search for the value in $a in the author index rather than
the title index.

This bug is four years old, the code may have changed since.
