Try these tips to narrow your search.
Try both singular and plural forms of words. Use an "*" in Academic Search Premier to get a variety of word endings.
If searching a compound word, try it as one word and as two words (for example, rain forest and rainforest).
If searching a word with an internal dash, search it in each database with and without the internal dash (for example, search both x-ray and xray).
