Running several queries simultaneously

You can combine several natural language conditions into a single query by using the Boolean operators <AND> or <OR> (or both) between the natural language phrases.

You must type these Boolean operators within angle brackets (< >).

Note: A natural language query is processed as a keyword query if you include <NOT> or <NEAR> operators anywhere in the expression.

To get results that include the following

Use

Both phrases

<AND> operator between the phrases

For example:(to heat water) <AND> (to produce steam)

or without parentheses: to heat water <AND> to produce steam

You can also use a period ( . ) between the phrases instead of typing <AND>.

For example: (to heat water).(to produce steam)

One phrase or the other, or both phrases

<OR> operator between the phrases

For example: (to heat water) <OR> (to produce steam)

or without parentheses: to heat water <OR> to produce steam
