A respective index entry corresponds to a respective term in one or more messages, and has a plurality of index components; a respective index component identifies a message associated with the respective term. The method further includes, responsive to receiving a first message; updating the index by: associating the first message with a conversation having one or more other messages; identifying text in the first message as quoted text based on text that occurs in one or more of the other messages; and updating, in the index, first-message index components that each includes an identifier of the first message, which includes original text index components and quoted text index components. The quoted text index components include information indicating that the corresponding terms are terms in the quoted text of the first message. |
