Problem: I need to combine a search in two fields (title, data) with or. (standard is and, and since now there is no chance to change this, afaik?)

A solution could be, to make two separate searches and join the searchResults, something like this:

<dtml-let title_search="Catalog.searchResults({'title':mysearchfield})" data_search="Catalog.searchResults({'data':mysearchfield})" complete_search="title_search + data_search">

and then iterate over the concatenated list:

<dtml-in complete_search size=20 start=query_start>

Well, I'd love to try this, but "title_search + data_search" doesn't work.

Error Type: TypeError Error Value: __add__ nor __radd__ defined for these operands

Any idea how to concatenate those two searchResults?

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. -- 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 ------------------------------------------
