in their very large scale web log study carried out in 2005 ( Jansen, Booth, & Spink, 2009 ). They analysed 1,523,793 queries executed on the Dogpile meta search engine and found the average number of search terms per query reaching 2.79 SD =1, 54 terms (p. 1365, Table 4 ). Almost 71 % of the search sessions consisted of only one query. The above log studies include few direct analyses of how users perceive term dependence in queries through phrase operators. It seems that overall users rarely query using fixed phrases: phrases have been used in queries at a

and comments about natural disasters and political uprisings travel at breakneck speed in Twitter or Google. Social media are becoming an important channel that can also greatly influence our perception of a certain topic. In economics, social media can have a significant effect on a firm’s reputation, sales, and even survival ( Kietzmann et al., 2011 ). Altmetrics ( Priem et al., 2010 ) use social media to estimate the early impact of publications or researchers. Dong and Bollen (2015) applied Google search-engine query data to detect consumer confidence indexes
