Does anybody know if you can search for a specific value through all the categories if you know the attrtype which are customized so you know the attrtypenr?I know that you can search like:search&lookfor1=complexquery&where1=(Attr_9207_2:67)But, I also know that this attribute has it's own attrtype=201I would like to find a way to search with something like:search&lookfor1=complexquery&where1=(Attrtype_201:67)
