Select the "GENERAL SEARCH" option (this option is selected by default)
When entering multiple terms, place quotation marks around the terms being searched
Boolean operator support is still in development, but limited support for Boolean operators is currently available. Boolean operators (such as "AND" "OR") may be used to connect search terms. No quotation marks are required when searching single terms connected by Boolean operators. For example: lamp and switch. However, multiple terms connected by boolean operators require quotation marks. For example: "lamp switch" and "electrical button"
