Future Directions of Query Understanding,h areas, such as cross-language IR. Moreover, there are many open questions and settings in query understanding that have not yet been fully explored. We will review some of these directions in this chapter, and we hope that researchers interested in query understanding will find them challenging and inspiring for future research directions.
