Database re-indexing howto

In order to get a database indexing started ...

  1. log into the ZMI (Site setup -> Zope Mgmt Interface) ;
  2. click the portal_catalog: the 7th tab is `Advanced' ;
    e.g. http://localhost:8080/plone4bio/portal_catalog/manage_catalogAdvanced 
    
  3. there you can find the way of clearing and rebuilding (or updating) the catalog; the way plone4bio works right now, you have to clear and rebuild it all.
