indextool - Sphinxsearch tool dump miscellaneous debug information
    about the physical index.
indextool {command} [options]
Sphinx is a collection of programs that aim to provide high
    quality fulltext search.
indextool is one of the helper tools within the Sphinx
    package. It is used to dump miscellaneous debug information about the
    physical index. Apart ghe dumping indextool can perform index
    verification, hence the indextool name rather than just indexdump.
The commands are as follows:
--dumpheader FILENAME.sph
quickly dumps the provided index header file without
  touching any other index files or even the configuration file. The report
  provides a breakdown of all the index settings, in particular the entire
  attribute and field list. Prior to 0.9.9-rc2, this command was present in CLI
  search utility.
--dumpconfig FILENAME.sph
dumps the index definition from the given index header
  file in (almost) compliant sphinx.conf file format.
--dumpheader INDEXNAME
dumps index header by index name with looking up the
  header path in the configuration file.
--dumpdocids INDEXNAME
dumps document IDs by index name. It takes the data from
  attribute (.spa) file and therefore requires docinfo=extern to
  work.
--dumphitlist INDEXNAME KEYWORD
dumps all the hits (occurences) of a given keyword in a
  given index, with keyword specified as text.
--dumphitlist INDEXNAME --wordid
  ID
dumps all the hits (occurences) of a given keyword in a
  given index, with keyword specified as internal numeric ID.
--htmlstrip INDEXNAME
filters stdin using HTML stripper settings for a given
  index, and prints the filtering results to stdout. Note that the settings will
  be taken from sphinx.conf, and not the index header.
--check INDEXNAME
checks the index data files for consistency errors that
  might be introduced either by bugs in indexer and/or hardware
  faults.
--strip-path
strips the path names from all the file names referenced
  from the index (stopwords, wordforms, exceptions, etc). This is useful for
  checking indexes built on another machine with possibly different path
  layouts.
--optimize-rt-klists
optimizes the kill list memory use in the disk chunk of a
  given RT index. That is a one-off optimization intended for rather old RT
  indexes, created by development versions prior to 1.10-beta release. As of
  1.10-beta releases, this kill list optimization (purging) should happen
  automatically, and there should never be a need to use this option.
The only currently available option applies to all commands and
    lets you specify the configuration file:
--config CONFIGFILE,
    -c CONFIGFILE
overrides the built-in config file names.
