Using insights from large-scale search logs, our findings clearly show that task is an additional relevant search unit that helps better understanding user's query reformulation patterns and predicting the next user's query. To design support processes for task-based search systems, we argue that we need to: (1) fully understand how user's task performed in natural settings drives the query reformulations changes; and (2) gauge the level of similarity of these changes trends with those observed in time-based sessions. With this in mind, we perform large-scale log analyses of users naturally engaged in tasks to examine query reformulations from both the time-based session vs. To identify query reformulation patterns, most of the previous works used large-scale log analyses segmented into time-based sessions.	./cache/cord-020903-qt0ly5d0.txt	./txt/cord-020903-qt0ly5d0.txt
