<h2>The Index</h2>
|
|
<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>
|
|
<br>
|
|
<h3>Indexing commands in Terminal</h3>
|
|
<p>There are several commands to manage the index:
|
|
<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>

|
|
<pre>Usage: mkindex [options] <attribute>

|
|
|
|
-d, --volume=PATH a path on the volume to which the index will be added,

<p><i><b>Note:</b> Only <b>new</b> files with that attribute come automatically into the index!</i><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" rel="nofollow">reindex</a>.

|
|
done, it will no longer be possible to use the query system to search for
