Using AND, OR, NOT

AND: You may use the connector "and" to combine terms in a KEYWORD search. "And" means that all search terms must be present in records retrieved.	For example:	grains and cereals
	retrieves only records in which BOTH "grains" and "cereals" appear.
	Using "and" NARROWS a search.
OR: You may use the connector "or" in a KEYWORD search to search on several alternative terms at once. Use "or" when you want to see all the records which contain ANY of the terms you specify.	For example:	mice or gerbils
	retrieves all records in which either "mice" or "gerbils" appears.
	For example:	galax* or nebula*
	retrieves all records in which either "galax" appears as a root word (galaxy, galaxies) or "nebula" appears as a root word (nebula, nebulae).
You may use "or" to search for variant spellings	For example:	cataloger or cataloguer
	Using "or" EXPANDS a search.
NOT: You may use the connector "not" (or "no") in a KEYWORD search to exclude a term. Using "not" narrows a search.	For example:	lizards not reptiles
	retrieves all records which contain "lizards" but excludes those which also contain the word "reptiles".
	For example	galax* not novel*
	retrieves all records which contain "galaxy" or "galaxies" but excludes those which also contain "novel" or "novels".
