[GeoNetwork-users] Modify search

Hi list,

I`m using a geonetwork 2.6 .war at tomcat 6.
I want to modify search options so users can only search at a certain region. So
I thought that I modify bounding box at config-gui.xml, ol_map.js,
main-page.xsl, ... and lucene files (config-lucene.xml, ...). But that did not
change my search results.

Any tips how to do so? Which files should I change?

Thanks for any suggestion.

best regards
Sarah
