Web search engine users normally enter a series of short Boolean queries. Some Web search services such as Ask Jeeves request users to enter question queries. We report findings from a study examining the nature of queries submitted to Ask Jeeves - a publicly accessible question and answer (Q&A) search engine. Some 30,000 queries from a dataset of 800,000 queries, or 3.75% of queries, were analyzed. Results include: (1) many queries not in question format, (2) four types of user queries: keyword, Boolean, question and request, and (3) common formats for question and request queries. Our findings provide an initial mapping of the structure and content of queries to QA systems.
