<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 />
The index is part of the filesystem and is kept for every volume/partition separately.</p>

<h1>Indexing commands in Terminal</h1> 
<p>There are several commands to manage the index:</p>
<ul> 
<li><b>lsindex</b> - Displays the indexed attributes on the current volume/partition.
<p>These are the attributes that are indexed by default:<br />

<li><b>mkindex</b> - Adds an attribute to the index of a volume/partition. 
<pre>Usage: mkindex [options] &lt;attribute&gt; 
Creates a new index for the specified attribute. 
 
  -d, --volume=PATH     a path on the volume to which the index will be added, 
                        defaults to current volume. 
  -t, --type=TYPE       the type of the attribute being indexed.  One of &quot;int&quot;, 
                        &quot;llong&quot;, &quot;string&quot;, &quot;float&quot;, or &quot;double&quot;. 
                        Defaults to &quot;string&quot;. 
      --copy-from       path to volume to copy the indexes from. 
  -v, --verbose         print information about the index being created 

</pre> 
<p>Only <b>new</b> files with that attribute come automatically into the index!<br />
Existing files have to be added manually by copying them and deleting the originals after that. Alternatively you can use the tool <a href="http://www.bebits.com/app/2033">reindex</a>. 
</p></li> 
<li><b>rmindex</b> - Removes an attribute from the index of a volume/partition. 
<pre>Usage: rmindex [OPTION]... INDEX_NAME 
 
Removes the index named INDEX_NAME from a disk volume.  Once this has been 
done, it will no longer be possible to use the query system to search for 
files with the INDEX_NAME attribute. 
 
  -d, --volume=PATH     a path on the volume from which the index will be 
                         removed 
  -h, --help            display this help and exit 
  -p, --pattern         INDEX_NAME is a pattern 
  -v, --verbose         print information about the index being removed 
 
INDEX_NAME is the name of a file attribute. 
 
If no volume is specified, the volume of the current directory is assumed.</pre>
