An article (Fisher et al., 2015) reports on a very interesting series of experiments, which explored the question of whether people feel that they have become more knowledgeable just through the act of searching. The answer is basically "yes", even when people don't find anything from the search.
"Searching for answers online leads to an illusion such that externally accessible information is conflated with knowledge “in the head” (Experiment 1a and b). This holds true even when controlling for time, content, and search autonomy during the task (Experiment 1c). Furthermore, participants who used the Internet to access explanations expected to have increased brain activity, corresponding to higher quality explanations, while answering unrelated questions (Experiment 2a). This effect is not driven by a misinterpretation of the dependent measure (Experiment 2b) or general overconfidence (Experiment 3) and is driven by querying Internet search engines (Experiment 4a-c)."

The title of this paper, just published online, says it all, really:
Rethlefsen, M., Farrell, A., Osterhaus Trzasko, L. and Brigham, T. (2015) Librarian co-authors correlated with higher quality reported search strategies in general internal medicine systematic reviews. Journal of clinical epidemiology. DOI: 10.1016/j.jclinepi.2014.11.025
The aim of the study was "To determine whether librarian and information specialist authorship was associated with better reported systematic review search quality. .... Systematic reviews from high impact general internal medicine journals were reviewed for search quality characteristics and reporting quality by independent reviewers using three instruments, including a checklist of Institute of Medicine Recommended Standards for the Search Process and a scored modification of the Peer Review of Electronic Search Strategies instrument. .... Systematic reviews with librarian or information specialist co-authors are correlated with significantly higher quality reported search strategies. To minimize bias in systematic reviews, authors and editors could encourage librarian engagement in systematic reviews including authorship as a potential way to help improve documentation of the search strategy." http://www.jclinepi.com/article/S0895-4356%2815%2900057-8/abstract

News article highlighting the fact that younger people aren't necessarily good at searching. This was following a talk by Google's Dan Rusell given at Glasgow University. I assume the content was similar to what he said at an earlier talk.
