bsp;&nbsp; Selection</b></h2>
</div><div><p>There are a number of ways elements in an <code>ova</code> can be selected. The library uses custom syntax to provide a shorthand for element selection. We use the function <code>indices</code> in order to give an examples of how searches can be expressed. Most of the functions like <code>select</code>, <code>remove!</code>, <code>filter!</code>, <code>smap!</code>, <code>smap-indexed!</code>, and convenience macros are all built on top of the <code>indices</code>
