And the outcome is the same, whether I search for: tag:,tag:'', or even tag:"". Even together with other tags. It is a tag in the sense that I can look for specific messages with that empty tag. if I try tag remove-all +untagged -- tag I get 1679 messages tagged with "untagged" as well as "". if I try: tag remove-all -- tag: I get no errors, notmuch will remove all tags, but the empty tag will remain. I'm running latest stable notmuch 0.37(?) on Debian/WSL2/Win11 if that helps. Thanks and keep up the great work! Pam ^ permalink raw reply [flat|nested] 4+ messages in thread

Even together with other tags. the TL;DR: Unfortunately this is just the default query parser in Xapian (that notmuch extends) falling back to looking for messages containing the word tag. The longer explanation: If you are curious, you can run $ NOTMUCH_DEBUG_QUERY=t notmuch count tag:"" Query string is: tag: Exclude query is: Query((((Kspam OR Kdeleted) OR Kmuted) OR Kbad-address)) Final query is: Query(((Tmail AND (Ztag@1 OR ZGtag@1 OR ZKtag@1 OR ZKtag@1 OR ZQtag@1 OR ZQtag@1 OR ZPtag@1 OR ZXPROPERTYtag@1 OR ZXFOLDER:tag@1 OR ZXFROMtag@1 OR ZXTOtag@1 OR ZXATTACHMENTtag@1 OR ZXMIMETYPEtag@1 OR ZXSUBJECTtag@1 OR ZXUList:tag@1)) AND_NOT (((Kspam OR Kdeleted) OR Kmuted) OR Kbad-address))) It's probably not too easy to read, but if squint you can see a bunch of prefixes other than K, which is tag. In case of surprising results, it's also worth trying the sexp query parser, as it is more likely to report errors, and in general handles corner cases better (the flip side of being less DWIM, I guess). NOTMUCH_DEBUG_QUERY=t notmuch count --query=sexp '(tag "")' Query string is: (tag "") Exclude query is: Query((((Kspam OR Kdeleted) OR Kmuted) OR Kbad-address)) Final query is: Query(((Tmail AND (<alldocuments> AND K)) AND_NOT (((Kspam OR Kdeleted) OR Kmuted) OR Kbad-address))) This query is easier to read, in particular K alone is the correct translation for an empty tag. For me this gets the expected answer 0. ^ permalink raw reply [flat|nested] 4+ messages in thread

Right. For the archive, if someone wants to find "tagless" in the sense of having no tags messages, sexp queries can do that as well $ notmuch count --query=sexp '(not (tag *))' This ends todays promotional feature on sexp queries ;) David ^ permalink raw reply [flat|nested] 4+ messages in thread
