Sorry about that - the message re zcatalog and reindexing just sent itself - unfinished! then crashed and failed to save in sent. v strange, but to complete ... If I edit an instannce of my zclass and change a keyword from say europe to Europe then the search works correctly but the following code snippet reveals that both europe AND Europe are now stored despite the fact that europe will not return any matches. If I update the catalog then europe disappears. My zclass calls <dtml-call reindex_object> after updating the properties. I know this works because the search does return correctly as I said. Clues? <dtml-in "Catalog.uniqueValuesFor('keywords')" sort=sequence-item> <a href="search?key=<dtml-var sequence-item url_quote_plus>"><dtml-var sequence-item></a><br> </dtml-in> Jonathan
