Since AND is the default, is this query identical to [ hello -world ]?

That's right. And it is also the same as hello AND -world since AND (must be all-caps) is a synonym for &.

May I suggest to remove "&" from this example? Otherwise readers may think that it's required for the NOT operator.

Searching for *only* a negative, e.g. `-world` or `-@mbostock` seems to trigger an error. A bunch of empty results render as it stalls for a while, and then eventually the page is replaced by "Oops, an unexpected error occurred." It seems like it should be conceivably possible to do this kind of search, returning everything that doesn't match the negated term, but if not perhaps a more explicit error message should appear right away.

The duplicate sentence is probably not intentional?

Thanks

Is there / will there be a way to search for notebooks that have file attachments? I just found myself looking for notebooks with a certain word in the title that have attachments because I am looking for a sample file of a particular type. Edit: Looking for notebooks with both a certain word in the title, and that also have file attachments. (side feature request: comment editing! :) )

"is:private", with and without quotation marks, matches published notebooks containing "is" and / or "private".

would be nice to search *collection:name*

Is there any temporal search? Notebooks modified since X date, or notebooks created before Y date?

author:@name is missing from this list.

author:@name was added and is:private should now work as intended.

+1 to Fil's *collection:name*

+1000 to search for collections

+1 to "collection:name": Seems I'm late to the party, but yes, would be super helpful!

So collection:name would search for notebooks in a collection called name? I guess this would be useful for very large collections?

I think so, could help to chain with a desired author. While this is all about searching for "notebooks", it could be useful to be able to search by "collections". (Ex. "Give me all the collections that include Plot in the title")

We now have collection:name as an option.

Works for owner / creator / author !== inquirer; "owner:@nikita-sharov" leads me to "Oops, an unexpected error occurred." I can't restrict the search to my notebooks only.

Works now as expected.

Works for user-name !== inquirer's user name; "@nikita-sharov" gives me 0 notebooks / "We couldn’t find any documents that matched your search query."

Sorry about that, it should work for @nikita-sharov now.

No problem; it does.
