[htdig] how to use regular expression while indexing

[Krzysztof G. <krz...@tu...>]

hello there,

i try to index some pages generated by a php-script. ok, that works,
but i want to index only such pages which matches one or more regular
expressions. for example i used

-include "^http://www.tu-clausthal.de/geomuseum/[^&]+&[^&]+$"

in an other indexer, but i can't use this with htdig with the
-limit_urls_to attribute. i've tried different variations of the
regular expression, but nothing works.
does any one knows, how to solve this problem? 
please mail me (krz...@tu...).

bye,

  krzysztof
