N2 - Enterprise query auto-completion (QAC) can allow website or intranet visitors to satisfy a need more efficiently than traditional searching and browsing. The limited scope of an enterprise makes it possible to satisfy a high proportion of information needs through completion. Further, the availability of structured sources of completions such as product catalogues compensates for sparsity of log data. Extended forms (X-QAC) can give access to information that is inaccessible via a conventional crawled index. We show that it can be guaranteed that for every suggestion there is a prefix which causes it to appear in the top k suggestions. Using university query logs and structured lists, we quantify the significant keystroke savings attributable to this guarantee (worst case). Such savings may be of particular value for mobile devices. A user experiment showed that a staff lookup task took an average of 61% longer with a conventional search interface than with an X-QAC system. Using wine catalogue data we demonstrate a further extension which allows a user to home in on desired items in faceted-navigation style. We also note that advertisements can be triggered from QAC. Given the advantages and power of X-QAC systems, we envisage that websites and intranets of the [near] future will provide less navigation and rely less on conventional search.
