“This crossover presents a challenge for site search: how do we meet the advanced needs of professional users without confusing members of the public who just want a simple answer? We can’t rely on the page they searched from to define which type of user they are; some people expect to search only within that department, but others have landed in the wrong place and need to find the general results. One of our priorities for this project was to start making search better for advanced users, without getting in the way of less experienced users.”
