1P 7.9.3 on Samsung device not limiting search to titles

1P_Timothy Thanks for your response and the information. I think the problem here is an aging and tired mind. Upon further reflection, I seriously doubt that I ever searched for 'Posteo' on my phone before, or if I did, it was only once or twice. I just got a new device, and I had to set up CalDAV, which required me to look up something stored in my Posteo entry. Once that got configured, I haven't had to search for "Posteo" again, and that is the only one that will return lots and lots of results (since my email address is often my username). Sorry for the noise and thanks for the great support. :)
