<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>

<li><b>mkindex</b> - Adds an attribute to the index of a volume/partition.
|
|
<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".

|
|
--copy-from path to volume to copy the indexes from.
|
|
-v, --verbose print information about the index being created
|
|
|
|
</pre>
|
|
<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>.
|
|

|
<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
