Improve Classification

One simple way to improve the Classify feature of DEVONthink is to exclude certain groups and documents from being used for classification. You could, e.g., exclude groups with indexed backup CDs or archived mailing lists from classification because they are ‘atypical’ for the contents of this database but you want to them in there anyway for easy access. To exclude an item from being used for classification, select it, open the Info panel (Tools > Show Info) and check ‘Exclude from classification.’
