Not out of the box.
Fields are parsed into tokens and queries search on tokens. An empty string has
no tokens for that field and a missing field has no tokens for that field.
If you really need to do this, then you’ll need to turn the empty string in a
special token that means “empty string”, c
Sounds interesting to test it out. I only played with 5.10 recently on
empty string search,it seems that *field:""* (double quotes) works, but
not *field:''* ( single quotes )

Can I search for the empty string? This is distinct from searching for
documents that don't have a certain fieldat all, which I can already do
with a clause of "*:* -field:[*TO *]"in my query.
