<h1>Index</h1>
|
|
|
|
<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>
|
|
|
|
<h2>
|
|
Indexing commands in Terminal</h2>
|
|
<p>There are several commands to manage the index:</p>
|
|
<ul>
|
|
<li><b>lsindex</b> - Displays the indexed attributes on the current volume/partition.<br />
|
|
These are the attributes that are indexed by default:</li>
|
|
</ul>

<li><b>mkindex</b> - Adds an attribute to the index of a volume/partition. </li>
|
|
</ul>
|
|
<pre>Usage: mkindex [options] <attribute>
|
|
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 "int",
|
|
"llong", "string", "float", or "double".
|
|
Defaults to "string".
|
|
--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 command <span class="cli">reindex</span>.
|
|
</p>
|
|
<ul>
|
|
<li><b>reindex</b> - Puts the attributes of existing files into the newly created index of a volume/partition. </li>
|
|
</ul>
|
|
<pre>Usage: reindex [-rvf] attr <list of filenames and/or directories>
|
|
-r enter directories recursively
|
|
-v verbose output
|
|
-f create/update all indices from the source volume,
|
|
"attr" is the path to the source volume
|

<li><b>rmindex</b> - Removes an attribute from the index of a volume/partition.</li>
|
|
</ul>
|
|
<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
|
