Simple email search is extremely slow

  1. Open the app
  2. Click on my “Sent” folder (which contains 862 messages total)
  3. Choose “Current folder” as the scope, and uncheck “Use server search if available” in the options menu.
  4. Search for a keyword like “minutes”

Expected: The search results should appear in a few seconds
Actual: More than a minute later, all I see is the spinning “wait” icon. It can take two minutes or more!

Anything unusual about my setup? Yes, in other local folders, I have 20 years of mail archives. But that should not affect searches that are scoped to the “Sent” folder.

Sometimes the search does produce a result quickly. But the above experience recurs multiple times per week.
