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

OR, either terms can be in the hit (good for

NOT, removes hits with the not term (Google products use the minus (-) sign.)
Database searches search every field in the detailed record. You can some searches by field. Great ones to use are author, and subject headings. Here is a video on using subject headings in three different databases
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).

Nesting also called Grouping keeps alike keywords together, and uses the OR within the parentheses and AND between. For example,
