What is Flatcurve?

EOL (End of Life) Notice

See Flatcurve Dovecot CE 2.3 EOL Notice.

This is a Dovecot FTS (Full Text Search) plugin to enable message indexing using the Xapian Open Source Search Engine Library.

The plugin relies on Dovecot to do the necessary stemming. It is intended to act as a simple interface to the Xapian storage/search query functionality.

This driver supports match scoring and substring matches, which means it is RFC 3501 (IMAP4rev1) compliant (although substring searches are off by default). This driver does not support fuzzy searches, as there is no built-in support in Xapian for it.

The driver passes all of the ImapTest search tests.
