Try: title_search[:] + data_search[:]. The result object from a Catalog query supports slicing, and this also works when there is only one result (because then the returned set is just a python list).
ZCatalog uses an object that avoids loading the whole result list into memory if it possibly can help it. Above solution will completely destroy this effort of course.

Hmm, no chance, Zope complains with:
Error Type: MemoryError Error Value:
that seems to be raised by the controlling method you mentioned
File /www/WWW/Zope/2.0.1/lib/python/DocumentTemplate/DT_Util.py, line 170, in careful_getslice File /www/WWW/Zope/2.0.1/lib/python/Products/ZCatalog/Lazy.py, line 109, in __getslice__ MemoryError: (see above)
and there ist only one item in each searchResult. Are the searchResult objects that big, that there has to be such a restriction?
Whoops. That's because the __getslice__ method is being called with sys.maxint. I didn't consult the Python language reference on this. Right, try this: title_search[:len[title_search]] + data_search[:len[data_search]] -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-7502100 Fax: +31-35-7502111 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------
