NAME

       notmuch-reindex - re-index matching messages

SYNOPSIS

       notmuch reindex [option ...] <search-term> ...

DESCRIPTION

       Re-index all messages matching the search terms.

       See notmuch-search-terms for details of the supported syntax for <search-term>.

       The  reindex  command  searches  for  all messages matching the supplied search terms, and
       re-creates the full-text index on these messages using the supplied options.

       Supported options for reindex include

       --decrypt=(true|nostash|auto|false)
              If  true,  when  encountering  an  encrypted  message,  try  to  decrypt  it  while
              reindexing,  stashing  any  session  keys discovered.  If auto, and notmuch already
              knows about a session key for the  message,  it  will  try  decrypting  using  that
              session  key  but  will not try to access the user's secret keys.  If decryption is
              successful, index the cleartext itself.

              nostash is the same as true except that it will not stash newly-discovered  session
              keys in the database.

              If  false,  notmuch  reindex  will  also  delete  any  stashed session keys for all
              messages matching the search terms.

              Be aware that the index  is  likely  sufficient  (and  a  stashed  session  key  is
              certainly sufficient) to reconstruct the cleartext of the message itself, so please
              ensure that  the  notmuch  message  index  is  adequately  protected.  DO  NOT  USE
              --decrypt=true or --decrypt=nostash without considering the security of your index.

              See also index.decrypt in notmuch-config.

EXAMPLES

       A  user  just received an encrypted message without indexing its cleartext.  After reading
       it (via notmuch show --decrypt=true), they decide that they want to index its cleartext so
       that  they  can  easily  find  it later and read it without having to have access to their
       secret keys:

          notmuch reindex --decrypt=true id:1234567@example.com

       A user wants to change their policy going forward to start indexing cleartext.   But  they
       also  want  indexed access to the cleartext of all previously-received encrypted messages.
       Some messages might have already been indexed in the clear (as in the example above). They
       can ask notmuch to just reindex the not-yet-indexed messages:

          notmuch config set index.decrypt true
          notmuch reindex tag:encrypted and not property:index.decryption=success

       Later,  the  user  changes their mind, and wants to stop indexing cleartext (perhaps their
       threat model has changed, or their trust in their index store has been shaken).  They also
       want  to  clear  all  of  their  old cleartext from the index.  Note that they compact the
       database afterward as a workaround for https://trac.xapian.org/ticket/742:

          notmuch config set index.decrypt false
          notmuch reindex property:index.decryption=success
          notmuch compact
