See also regex(7).
"""a '\' followed by any other character(!) (matching that character taken as an ordinary character, as if the '\' had not been present(!))"""</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">The sorcery astDB wizzard does not handle regex correctly if the pattern begins with an anchor character.
This patch attempts to convert the anchored regex pattern to a prefix pattern supported by astDB for performance reasons. If it is not able to convert the pattern it gets all astDB members of the family and then does a normal regex pattern matching on the resulting records retrieved.</pre>

More complex patterns fallback to getting all astDB family records and searching them by regex.</pre>
