  FWIW in 1.1beta releases, you can enable the "squat" plugin and get 
  full-text indexed search already.
  
  Timo's working on improvements, as you can see, and a replacement, but 
  don't forget that Squat is real and pretty fast.
  
  To enable it, do:
  
  1. In the "protocol imap {" section of the config, add this line to the 
  end:
  
  	 mail_plugins = fts fts_squat
  
  Do that just before the close curly brace.
  
  2. If you have a "plugin {" section of the dovecot.conf, do 2(a). 
  Otherwise, do 2(b).
  
  2a. In the "plugin {" section, add this line to the end:
  
    fts = squat
  
  2b. At the end of the file, write this:
  
    plugin {
        fts = squat
    }
  
  That should be all!  SEARCH TEXT will be, shall we say, accelerated. (Note 
  that indexes have to be generated sometime, so the way things are now 
  they're generated at the first SEARCH TEXT.)

Thanks for this list of steps, I've been intending to test it and was just about
getting ready to ask the same question.  Your email would be mice content to
throw on the dovecot wiki under fts (currently empty)
