<p>Load indexes and keep them open in <em class="parameter"><code>ctx</code></em>

<p>If user will do more than one or two lookups, insertions, deletions, most
likely it's good to call this function first. Particularly in a daemon like
udev that on bootup issues hundreds of calls to lookup the index, calling
this function will speedup the searches.</p>
