Make it possible to search for records lacking a MARC field in Create Lists
I recently wanted to run a search for all records that matched certain criteria and did not have an 856 field. However, Create Lists does not currently have a "lacks field" option. It would be very helpful to be able to search for records that do not have certain fields.

The product team will review this idea for consideration for a future release.

Since the goal is already doable, why don't we rephrase this idea as "Make it EASIER to search..."? The solution could then be to extend the "not exists" operator to more fields in more record types.
This admittedly gets a little tricky for fixed-length fields and would have to be implemented more sparingly there. Not Exists already works on Item Due Date; I'd like to see it work on fixed fields which are not assigned a default value, like Item Sticky Status.

It is also possible to do this with a JSON like this:
{
"target": {
"record": {
"type": "bib"
},
"field": {
"marcTag": "020"
}
},
"expr": {
"op": "not_exists",
"operands": [
"",
""
]
}
}But come on, the system can clearly do this. It should be easily available in the interface.

Having a more obvious, built-in feature for this kind of search would probably be more user-friendly than the method that is currently required.

You should be able to search bib records that lack the 856 field by the criteria below:
BIBLIOGRAPHIC MARC Tag 856 equal to ""
b !856 = <blank>
