Hello ! I'm trying to use a catalog in order to enable search queries based on metadata of the objects (ExtFiles) in a directory. As users will add new objects, the catalog must be updated, which (the catalog updating) I figured must be done "by hand", that is, by telling the catalog to update itself in the same script which also does the uploading of the ExtFiles. By looking in the ZopeBook I was able to catalog_object() each new ExtFile as it is uploaded, but that doesn't also update the indexes and the vocabulary. How can THAT be achieved ? I haven't noticed any such function in the API reference manual. I tried to look in the source of the "advanced" page of the catalog manager and see what the "update catalog" button does, but it's a bit too tough for me :-) Thanks ! andrei
