Only columns that are not set. This seems most consistent with other "false" searches. For the casual user, the idea of searching for "false" comes as a surprise, but when you tell them it means it's "empty" they quickly learn to use it to find empty Comments and Covers.

Columns that are set (both Yes and No). This seems most consistent with the "false" search. "True" means the column is not empty.

When considering the choice, note that if col:yes matches only columns containing 'Yes' and col:no only columns containing No, then:
- a search for 'not col:yes' would get both No and not-set.
- a search for 'not col:no' would get both Yes and not-set.
- 'not (col:yes or col:no)' would get only not-set columns.

That's what an advanced level user would probably expect, and the less advanced user probably wouldn't structure any searches like that.

Alternative: the value No goes away, leaving as possible values Yes and not-set, making the column effectively two-valued.

I don't like this option. It drastically reduces the value of the column. Anyone who wants this behavior can easily globally set all to "No" before they start.

2. Text/multiple and text/single columns will appear in the tag browser as categories. Should they disappear when they are removed from the GUI (config/interface/uncheck column)? If so, should the standard categories also disappear if unchecked? For example, if I take Publisher off the GUI, should it also disappear from the tags browser?

IMHO - No.

The question: how should a restriction be visually indicated? Options I have thought of: a) set the 'number of books' text next to the search box to 'restricted' instead of 'all books', b) color that same box/text (what color)?, or c) be indicated by the fact that the restriction selection box has something in it. Ideas?

All of the above - Yellow. My initial thought is that I'd like the search box, the saved search box and the restriction box all to be visually indicated by color when a restriction is in effect. I can see myself wondering why my search for X is failing when a restriction that excludes X is in effect. Having color at the search and saved search would remind me that I already have the restriction operating when I go to search for something within that restricted set.
