datasets</h1>
</div>
</div>
</div>
<p>As of <span class="application">Recoll</span> 1.24, it has
become easy to build self-contained datasets including a
<span class="application">Recoll</span> configuration
directory and index together with the indexed documents, and
to move such a dataset around (for example copying it to an
USB drive), without having to adjust the configuration for
querying the index.</p>
<div class="note" style=
"margin-left: 0.5in; margin-right: 0.5in;">
<h3 class="title">Note</h3>
<p>This is a query-time feature only. The index must only
be updated in its original location. If an update is
necessary in a different location, the index must be
reset.</p>
</div>
<p>The examples below will assume that you have a dataset
under <code class="filename">/home/me/mydata/</code>, with
the index configuration and data stored inside <code class=
"filename">/home/me/mydata/recoll-confdir</code>.</p>
<p>In order to be able to run queries after the dataset has
been moved, you must ensure the following:</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc;">
<li class="listitem">
<p>The main configuration file must define the
<a class="link" href=
"#RCL.INSTALL.CONFIG.RECOLLCONF.ORGIDXCONFDIR">orgidxconfdir</a>
variable to be the original location of the
configuration directory (<code class=
"filename">orgidxconfdir=/home/me/mydata/recoll-confdir</code>
must be set inside <code class=
"filename">/home/me/mydata/recoll-confdir/recoll.conf</code>
in the example above).</p>
</li>
<li class="listitem">
<p>The configuration directory must exist with the
documents, somewhere under the directory which will be
moved. E.g. if you are moving <code class=
"filename">/home/me/mydata</code> around, the
configuration directory must exist somewhere below this
point, for example <code class=
"filename">/home/me/mydata/recoll-confdir</code>, or
<code class=
"filename">/home/me/mydata/sub/recoll-confdir</code>.</p>
</li>
<li class="listitem">
<p>You should keep the default locations for the index
elements (they are relative to the configuration
directory by default). Only the paths referring to the
documents themselves (e.g. <code class=
"literal">topdirs</code> values) should be absolute (in
general, they are only used when indexing anyway).</p>
</li>
</ul>
</div>
<p>Only the first point needs an explicit user action, the
<span class="application">Recoll</span> defaults are
compatible with the second one, and the third is natural.</p>
<p>If, after the move, the configuration directory needs to
be copied out of the dataset (for example because the thumb
drive is too slow), you can set the <a class="link" href=
"#RCL.INSTALL.CONFIG.RECOLLCONF.CURIDXCONFDIR">curidxconfdir</a>,
variable inside the copied configuration to define the
location of the moved one. For example if <code class=
"filename">/home/me/mydata</code> is now mounted onto
<code class="filename">/media/me/somelabel</code>, but the
configuration directory and index has been copied to
<code class="filename">/tmp/tempconfig</code>, you would set
<code class="literal">curidxconfdir</code> to <code class=
"filename">/media/me/somelabel/recoll-confdir</code> inside
<code class="filename">/tmp/tempconfig/recoll.conf</code>.
<code class="literal">orgidxconfdir</code> would still be
<code class="filename">/home/me/mydata/recoll-confdir</code>
in the original and the copy.</p>
<p>If you are regularly copying the configuration out of the
dataset, it will be useful to write a script to automate the
procedure. This can't really be done inside <span class=
"application">Recoll</span> because there are probably many
possible variants. One example would be to copy the
configuration to make it writable, but keep the index data on
the medium because it is too big - in this case, the script
would also need to set <code class="literal">dbdir</code> in
the copied configuration.</p>
<p>The same set of modifications (<span class=
"application">Recoll</span> 1.24) has also made it possible
to run queries from a readonly configuration directory (with
slightly reduced function of course, such as not recording
the query history).</p>

<chapter id="RCL.MOVABLE">
<title>Movable datasets</title>
<para>As of &RCL; 1.24, it has become easy to build self-contained
datasets including a &RCL; configuration directory and index together
with the indexed documents, and to move such a dataset around (for
example copying it to an USB drive), without having to adjust the
configuration for querying the index.</para>
<note><para>This is a query-time feature only. The index must only be
updated in its original location. If an update is necessary in a
different location, the index must be reset.</para></note>
<para>The examples below will assume that you have a dataset under
<filename>/home/me/mydata/</filename>, with the index configuration and
data stored inside
<filename>/home/me/mydata/recoll-confdir</filename>.</para>
<para>In order to be able to run queries after the dataset has been
moved, you must ensure the following:
<itemizedlist>
<listitem><para>The main configuration file must define the <link
linkend="RCL.INSTALL.CONFIG.RECOLLCONF.ORGIDXCONFDIR">orgidxconfdir</link>
variable to be the original location of the configuration directory
(<filename>orgidxconfdir=/home/me/mydata/recoll-confdir</filename>
must be set inside
<filename>/home/me/mydata/recoll-confdir/recoll.conf</filename> in
the example above).</para></listitem>
<listitem><para>The configuration directory must exist with the
documents, somewhere under the directory which will be
moved. E.g. if you are moving <filename>/home/me/mydata</filename>
around, the configuration directory must exist somewhere below this
point, for example
<filename>/home/me/mydata/recoll-confdir</filename>, or
<filename>/home/me/mydata/sub/recoll-confdir</filename>.</para></listitem>
<listitem><para>You should keep the default locations for the index
elements (they are relative to the configuration directory by
default). Only the paths referring to the documents themselves
(e.g. <literal>topdirs</literal> values) should be
absolute (in general, they are only used when indexing
anyway).</para></listitem>
</itemizedlist>
</para>
<para>Only the first point needs an explicit user action, the &RCL;
defaults are compatible with the second one, and the third is
natural.</para>
<para>If, after the move, the configuration directory needs to be
copied out of the dataset (for example because the thumb drive is too
slow), you can set the <link
linkend="RCL.INSTALL.CONFIG.RECOLLCONF.CURIDXCONFDIR">
curidxconfdir</link>, variable inside the copied configuration to
define the location of the moved one. For example if
<filename>/home/me/mydata</filename> is now mounted onto
<filename>/media/me/somelabel</filename>, but the configuration
directory and index has been copied to
<filename>/tmp/tempconfig</filename>, you would set
<literal>curidxconfdir</literal> to
<filename>/media/me/somelabel/recoll-confdir</filename> inside
<filename>/tmp/tempconfig/recoll.conf</filename>.
<literal>orgidxconfdir</literal> would still be
<filename>/home/me/mydata/recoll-confdir</filename> in the original and
the copy.</para>
<para>If you are regularly copying the configuration out of the
dataset, it will be useful to write a script to automate the
procedure. This can't really be done inside &RCL; because there are
probably many possible variants. One example would be to copy the
configuration to make it writable, but keep the index data on the
medium because it is too big - in this case, the script would also need
to set <literal>dbdir</literal> in the copied configuration.</para>
<para>The same set of modifications (&RCL; 1.24) has also made it
possible to run queries from a readonly configuration directory (with
slightly reduced function of course, such as not recording the query
history).</para>
