NAME
       xapian-compact - Compact a database, or merge and compact several

SYNOPSIS
       xapian-compact [OPTIONS] SOURCE_DATABASE... DESTINATION_DATABASE

DESCRIPTION
       xapian-compact - Compact a database, or merge and compact several

OPTIONS
       -b, --blocksize=B
              Set the blocksize in bytes (e.g. 4096) or K (e.g. 4K) (must be
              between 2K and 64K and a power of 2, default 8K)

       -B, --backend=B
              Set the output backend.  Supported values are 'glass' and
              'honey'.  By default input's backend is used.  At present only
              glass to honey conversion is implemented - otherwise the backend
              must be the same.

       -n, --no-full
              Disable full compaction

       -F, --fuller
              No effect for glass since Xapian 1.4.31

       -m, --multipass
              If merging more than 3 databases, merge the postlists in
              multiple passes (which is generally faster but requires more
              disk space for temporary files)

       --no-renumber
              Preserve the numbering of document ids (useful if you have
              external references to them, or have set them to match unique
              ids from an external source).  Currently this option is only
              supported when merging databases if they have disjoint ranges of
              used document ids

       -s, --single-file
              Produce a single file database

       --help display this help and exit

       --version
              output version information and exit
