Search string may contain the logical operators AND and OR and the operands () and "". AND searches for both words or phrases, while OR searches for one or the other. If the search string uses AND and OR at the same time, the AND operation takes priority, unless you enclose the OR operation in parentheses, as in (A or B) and C. To find an exact phrase, such as "lesotho population", enclose the phrase in quotes.
Please refer to the following examples:

• Search for Population to find all series that contain Population.
• Search for Household or Housing to find all series that contain either Household or Housing indicators.
• Search for Household and Housing to find all series that contain both Household and Housing indicators.
• Search for (Household or Housing ) "Economic dependency" to find all series that contain either Household or Housing indicators or the phrase "Economic dependency".
