[fix] engine: Anna's Archive - grep results from '.js-scroll-hidden' elements 

The renderuing of the WEB page is very strange; except the firts position all
other positions of Anna's result page are enclosed in SGML comments.  These
cooments are *uncommented* by some JS code, see query of the class
'.js-scroll-hidden' in Anna's HTML template [1].
