For those of you who search the mainstream databases such as Dialog, STN, OVID, Datastar and Lexis Nexis attached is a cheat sheet on how search operators compare between databases. It’s not exact, since every data provider has its peculiarities, and search options are different between databases on each provider.
Anyway, even with the above caveat I hope you find it useful
Please feel free to send suggestions for additional items to be included and I will update as needed. (I initially kept this brief as I wanted to use it as promo material and keep it clean.)
