• receiving a keyword from the user terminal in communication with the mail service system over the network, the keyword being different from the tag indicating the card item;
• in response to receiving the keyword, searching for and retrieving mail data that includes the keyword;
• configuring a separate mail list for at least one card item by selecting a subset of mail data among the retrieved mail data that is determined as a result of said searching to include the keyword in the at least one card item, wherein the subset of mail data includes a plurality of pieces of mail data such that the configured separate mail list includes the plurality of pieces of mail data;
• creating a mail card that includes the tag indicating the at least one card item, an interactive link to the configured separate mail list, and summary information on mail data among the selected subset of mail data that includes the keyword in a description of the at least one card item;
• and
• creating a search result that includes the created mail card, and providing the created search result to the user terminal over the network in response to receiving the keyword, wherein the search result, including at least the mail card with the included tag, is displayed on a display of the user terminal;
• wherein the creating and the providing of the search result comprises creating the search result to further include information about a portion of the retrieved mail data that does not include the selected subset of mail data, and creating and providing the search result to include and display the mail card and display the included tag within the mail card at a top end of the displayed search result.
