There are features on databases or eResources that will make your searches more productive. Investigate them for your resource.
Check out:
Do not filter by full-text - you can get articles via inter-library loan where the library does not have them in the collection
Create a personal account on the eResource (database) where you can save your search results, searches and set up search alerts to let you know when new articles are added. (Create a separate spreadsheet for backup- though!).
Create a RefWorks account and export your results to it.
Your information librarian will be able to advise with all of these points.
All databases (eResources) have tools to improve your searching.
Use the onboard help to find out how your database deals with proximity searching (how close words appear next to each other) and controlled language ( thesaurus, MESH headings, Subject terms) All of these can improve your searches. The basic " " quote marks will work for all databases.
