Locate definition for the same lujvo that is of a different form

[Pendrokar]

For example, vlasisku is unable to find the definition for vorgreku:
http://vlasisku.lojban.org/vorgreku
The autocorrect suggestion is only a coincidence of elastic search.

A valid definition already exists, just in a different form:
http://vlasisku.lojban.org/vrogreku

The definitions are coming from lojban/jbovlaste, which currently has to provide different definitions for the same tanru in lujvo form.
