I have a large ZCatalog (330,000+ objects) that has been in production for nearly a year. One particularly important index keeps track of client names so that users can quickly search by client. The index is a ZCTextIndex called 'clientString'. Sometime very recently, my query began raising an exception when users try to search on the term 'Smith'. My best guess is that one of the records in the catalog containing the word 'Smith' has been corrupted somehow. The query looks like this: container.catalogOfEFRObjects.searchResults({'clientString':'Smith'}) The traceback looks like this: Traceback (innermost last): ...
