Perhaps you should try some spelling variations:
investment services » government services, treatment services, investment choices
investment series » investment barriers, investment treaties, investment schemes
poor investment » power investments, sector investment
kept rates » heat rates
repo rates » repo rate
kept poor » neet poor

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: (( h. kept poor investment services ) OR ( h. ((kept rates) OR (repo rates)) investment series ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( h. kept poor investment services ) or ( h. ((kept rates) OR (repo rates)) investment series ))~".
• Adding a wildcard symbol may retrieve word variants: (( h. kept poor investment services ) or ( h. ((kept rates) OR (repo rates)) investment series ))*.
