In this work, we provide a detailed characterization of such queries based on an analysis of a real-life query log. Our experimental setup allows us to characterize the queries with few/no results and compare the mechanisms employed by the major search engines in handling them.EnglishQuery difficultySearch result qualityWeb search enginesQuery difficultyQuery logsSearch resultsUser queryWeb search qualityWeb search queriesKnowledge managementOnline searchingSearch enginesWebsitesConference Paper10.1145/2396761.2398560
