Why is search so slow? Missing item / Search parameters

Searches on Microsoft accounts are inherently slow, additionally we only search the Inbox of Microsoft accounts . IMAP accounts will only search for the specific string.

Our searches are passed directly to the provider, each provider has their own search algorithms. We have no control over what the provider returns.

You can improve the speed of searches by implementing a search date period in your application that for example only searches the last 3 months by default.

subject:Test (received>12/31/2021)
  • Disallow searching with less than 3 characters
  • Limit 1 search per 30 seconds
  • Ensure you apply filters by default 
    • from:
    • subject:
    • received in the last three months.

IMAP searches:

IMAP unlike Google and Microsoft searches does not  search for objects %like% , the search term must match 100%
