Hi, I'd like to search for all emails with a defined email header. According notmuch-search(1) [1] this should be a trivial. But I got a very limited results $ notmuch count --exclude=false "X-Mailinglist" 2 where simple $ grep -R "^X-Mailinglist" . ./new/1360572283.M251897P7737Q200Ra1da4988633e0842.zelvantb:X-Mailinglist: opensuse-factory ./new/1360315438.M35384P12994Q25807R1a5203f9da8b1b28.zelvantb:X-Mailinglist: opensuse ./new/1360315441.M705450P13019Q25830R71a1deb928bb7cf3.zelvantb:X-Mailinglist: opensuse ./new/1360315436.M459220P12984Q25797R13d6f3a1f39d2148.zelvantb:X-Mailinglist: opensuse ./new/1360315381.M437845P12634Q25464R3bccd68f2b8fd54f.zelvantb:X-Mailinglist: opensuse ./new/1360315556.M414918P13763Q26528R614e01d632d1c3d8.zelvantb:X-Mailinglist: opensuse ^C shows me, there are hundreds and hundreds of such emails in my local maildir. I use very simple setup generated by notmuch-setup with a basic set of inbox, undread signed and similar tags. Can anyone point me on a correct query string for such search? I have following versions of xapian and notmuch installed $ rpm -q libxapian22 notmuch libxapian22-1.2.8-2.1.2.x86_64 notmuch-0.14-20.3.x86_64 [1] http://notmuchmail.org/manpages/notmuch-search-1/ BTW: please CC me in a reply, I've just signed to the ML, but did not get the you-were-subscribed email from mailman. Thanks for a help Michal Vyskocil
