Googling with a bibliography.

means Systematic investigation into a subject to discover or confirm facts, usually with enough rigor that you have to show your work.

from From French recherche, built on chercher 'to search,' itself descending from Latin circare 'to go around, explore' (the root of 'circle'). The re- prefix piles on top for emphasis — so at bottom it means something like 'to search thoroughly, again and again,' which is either a noble ideal or a prediction of every literature review ever written.

word trap
re- here means thorough, not repeated
peer review
other experts check your work before publication
null results
most studies fail to confirm their hypothesis
citation chains
one bad source can propagate for decades
