When available, use Advanced Search pages rather than Basic Search pages.
Combine different concepts with AND, which = all of the words e.g. biosolids AND agriculture
Truncate: metabol* will search for metabolism, metabolic, metabolize etc. Note: the * truncation does NOT work in Science Direct.
Think up alternate terms for your concepts
Combine these alternate terms with OR, which = any of the words e.g. uptake OR metabolize OR absorb
When an article database allows you to, use both AND and OR in a search.
Alternatively, on sites like google scholar, use the All words / Any words / Exact phrase options.
Look for limiters provided within article databases that will exclude popular magazines, letters to the editor, articles published in the 19th Century, etc.
Experiment with where your words are searched: All fields, Keywords, etc.
