Find a method that works with you to keep track. You can try this Search Log. It is divided into the three parts of methodical searching.
AND, OR & NOT
AND, both terms must be in the hits
OR, either terms can be in the hit (good for
synonyms)
NOT, removes hits with the not term (Google products use the minus (-) sign.)
As part of proximity searches, you can specify how close, and in what order, you want the search terms to appear. The proximity operators are usually composed of a letter (N) or word (NEAR) and a number (to specify the number of words appearing between your search terms). For EBSCOHost databases use the letter (N) and Google products use AROUND(#).
Nesting also called Grouping keeps alike keywords together, and uses the OR within the parentheses and AND between. For example,
