[Zope] Text *and* field indexes in ZCatalog?

[Paul Everitt]

Yep.  Define a "virtual" field that returns a concatenation of all the
real "fields" that you want indexed, then register that with the
ZCatalog as the thing that supplies the text.  The "virtual" field could
be defined up above all the XML Documents and use the magic of
acquisition to bind it to all the actual documents.

You have a number of options for defining the virtual field.  An
external method is straightforward, or an DTML Method that used the
wonderful, wonderful new <!--#return--> tag.

Alternatively, and this is where it gets truly fun, you could start
looking at giving your XML Documents a "brain".  I'm not sure if this is
ready for prime time yet though.
