When you create a search string, there are things to remember:
- Always use parentheses around your search words to "preserve the logic" of your string.
Example: (Jelly OR Jam) AND peanut butter =/= Jelly OR (Jam AND peanut butter).
- Always keep your OR statements in one line and use parentheses--this prevents issues of the default process order of AND, OR, and NOT in various databases
- Using quotation marks around phrases will look for exact matches, only.
Example: "bed bugs" will not find "bed bug". Instead search for bed AND bug*, without the quotes, to get both variations.
