When an email arrives, the system files any attachments automatically. It then scans the content of the email in search of key words which may describe the attachments. Those words are added to the filed documents as tags. You can see those tags in the ‘tags’ section of each document. These tags are used when searching for your files. Imagine a document called ‘insurance.pdf’ that is sent by your adviser. Imagine that the email contains a sentence ‘I attach your car insurance policy for your Saab’. The system will take ‘Saab’, ‘insurance’, and ‘policy’ as key words that describe ‘insurance.pdf’. Next time you type ‘Saab’ in the search box, the system will fetch ‘insurance.pdf’.
