Dear Colleagues Can anyone help with an Ovid Medline V Pubmed question? A research colleague of mine has got the following odd results when conducting her search and has asked me to look into it. She searched the word 'mindfulness' in the following ways: Ovid Medline (R) searching all fields using .af. = 424 hits Pubmed basic search = 178722 hits Pubmed Advanced searching all fields using the all fields tag = 364 hits She knows Medline and Pubmed are different but was expecting the 178722 hits on Ovid. 424 was the most she could get and seems very low. Any answers? Thanks Kate
