NAME

       htload - reads in an ASCII-text version of the document database


SYNOPSIS

       htload [options]


DESCRIPTION

       Htload   reads in an ASCII-text version of the document database in the
       same form as the  -t  option  of  htdig  and  htdump.  Note  that  this
       will  overwrite  data  in  your  databases, so this should be used with
       great care.


OPTIONS

       -a     Use alternate work  files.  Tells  htload  to  append  .work  to
              database  files,  allowing  it  to  operate  on  a second set of
              databases.

       -c configfile
              Use the specified configfile instead of the default.

       -i     Initial.  Do  not use any old databases. This is accomplished by
              first erasing the databases.

       -v     Verbose mode. This doesn’t have much effect.


File Formats

       Document Database
              Each  line in the file starts with the document id followed by a
              list of fieldname : value separated by tabs. The  fields  always
              appear in the order listed below:

       u      URL

       t      Title

       a      State (0 = normal, 1 = not found, 2 = not indexed, 3 = obsolete)

       m      Last modification time as reported by the server

       s      Size in bytes

       H      Excerpt

       h      Meta description

       l      Time of last retrieval

       L      Count of the links in the document (outgoing links)

       b      Count of the links to the document (incoming links or backlinks)

       c      HopCount of this document

       g      Signature of the document used for duplicate-detection

       e      E-mail address to use for a notification message from htnotify

       n      Date to send out a notification e-mail message

       S      Subject for a notification e-mail message

       d      The   text   of  links  pointing  to  this  document.  (e.g.  <a
              href="docURL">description</a>)

       A      Anchors in the document (i.e. <A NAME=...)

       Word Database
              While htdump and  htload  don’t  deal  with  the  word  database
              directly, it’s worth mentioning it here because you need to deal
              with it when copying the ASCII  databases  from  one  system  to
              another.  The initial word database produced by htdig is already
              in ASCII format, and a binary  version  of  it  is  produced  by
              htmerge,  for  use by htsearch. So, when you copy over the ASCII
              version of the document database produced by htdump, you need to
              copy  over  the  wordlist  as  well, then run htload to make the
              binary document database on the target system, followed by  run-
              ning htmerge to make the word index.

       Each line in the word list file starts with the word
              followed  by  a list of fieldname : value separated by tabs. The
              fields always appear in the order listed below,  with  the  last
              two being optional:

       i      Document ID

       l      Location of word in document (1 to 1000)

       w      Weight of word based on scoring factors

       c      Count of word’s appearances in document, if more than 1

       a      Anchor number if word occurred after a named anchor
