Perhaps you should try some spelling variations:
primary development » summary development, preliminary development, property development
smart development » market development, port development, market developments
rice development » mine development, site development, service development
poverty declines » poverty decline, poverty lines, poverty line

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: cfaa ((((primary development) OR (smart development))) OR (rice development)) poverty declines~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cfaa ((((primary development) OR (smart development))) or (rice development)) poverty declines~".
• Adding a wildcard symbol may retrieve word variants: cfaa ((((primary development) OR (smart development))) or (rice development)) poverty declines*.
