  60 <h1>Index</h1>
  61
  62 <p><a href="attributes.html">Attributes</a> and <a href="queries.html">Queries</a> are key features of Haiku. While attributes are useful on their own, to display additional information on a file, for a query on them, they need to be indexed. It puts them into a lookup table, which in turn makes queries lightning fast.<br />
  63 The index is part of the filesystem and is kept for every volume/partition separately.</p>
  64
  65 <h2>
  66 Indexing commands in Terminal</h2>
  67 <p>There are several commands to manage the index:</p>
  68 <ul>
  69 <li><b>lsindex</b> - Displays the indexed attributes on the current volume/partition.<br />
  70 These are the attributes that are indexed by default:</li>

 113 <li><b>mkindex</b> - Adds an attribute to the index of a volume/partition. </li>
 114 </ul>
 115 <pre>Usage: mkindex [options] &lt;attribute&gt;
 116 Creates a new index for the specified attribute.
 117
 118   -d, --volume=PATH     a path on the volume to which the index will be added,
 119                         defaults to current volume.
 120   -t, --type=TYPE       the type of the attribute being indexed.  One of "int",
 121                         "llong", "string", "float", or "double".
 122                         Defaults to "string".
 123       --copy-from       path to volume to copy the indexes from.
 124   -v, --verbose         print information about the index being created
 125
 126 </pre>
 127 <p>Only <b>new</b> files with that attribute come automatically into the index!<br />
 128 Existing files have to be added manually by copying them and deleting the originals after that. Alternatively you can use the command <span class="cli">reindex</span>.
 129 </p>
 130 <ul>
 131 <li><b>reindex</b> - Puts the attributes of existing files into the newly created index of a volume/partition. </li>
 132 </ul>
 133 <pre>Usage: reindex [-rvf] attr &lt;list of filenames and/or directories&gt;
 134   -r    enter directories recursively
 135   -v    verbose output
 136   -f    create/update all indices from the source volume,
 137         "attr" is the path to the source volume
 138
 139 </pre>
 140 <ul>
 141 <li><b>rmindex</b> - Removes an attribute from the index of a volume/partition.</li>
 142 </ul>
 143 <pre>Usage: rmindex [OPTION]... INDEX_NAME
 144
 145 Removes the index named INDEX_NAME from a disk volume.  Once this has been
 146 done, it will no longer be possible to use the query system to search for
 147 files with the INDEX_NAME attribute.
 148
 149   -d, --volume=PATH     a path on the volume from which the index will be
 150                          removed
 151   -h, --help            display this help and exit
 152   -p, --pattern         INDEX_NAME is a pattern
 153   -v, --verbose         print information about the index being removed
 154
 155 INDEX_NAME is the name of a file attribute.
 156
 157 If no volume is specified, the volume of the current directory is assumed.</pre>
