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 "Gini coefficient", enclose the phrase in quotes. Please refer to the following examples:

• Search for Western Cape to find all series that contain Western Cape.
• Search for Population or Poverty Gap Ratio to find all series that contain Population or Poverty Gap Ratio indicators.
• Search for Population and Poverty Gap Ratio to find all series that contain both Population and Poverty Gap Ratio indicators.
• Search for (Population or Poverty Gap Ratio) "Gini coefficient" to find all series that contain either Population or Poverty Gap Ratio indicators or the phrase "Gini coefficient".
