Search Tips

Wildcards Symbol (*)

The wildcard symbol (*) can be used in place of letters or characters in query words to search for different permutations of a word.

Examples:	hemo*	matches hemolytic, hemophilia and hemophilia
	*NA	matches DNA and RNA
	*tet**	matches text and test
	BCL*	matches bcl-1/JH and bcl-2/JH
	virus*	matches virus or viruses
	*glucan*	matches beta-1,3-d-Glucan

Boolean Parameters

Search terms can be a single word or several words. The search engine automatically inserts and between words if nothing else is specified, so the Boolean term and can be omitted in search terms. For example, searching for tissue assay is the same as searching for tissue AND assay.
