I am interested in understanding the website's search functionality and how to find content related to specific topics. Please use the search bar to find articles containing the keyword '부동산' (real estate). After performing the search, identify the total number of search results, and list the title and publication date of the first three articles displayed.
Navigate to the homepage of economist.co.kr. Locate the 'SEARCH' link (id: 415) and click it. Enter '부동산' into the search input field. Execute the search. Identify the total number of search results. Extract the title and publication date of the first three articles listed in the search results.
The agent successfully navigates to the search interface. The agent successfully performs a search for '부동산'. The agent states the total number of search results found for '부동산'. The agent provides the title and publication date for the first three articles from the search results.
