Perhaps you should try some spelling variations:
range planning » change planning, care planning, face planning
land planning » based planning, road planning, dam planning
human gender » bhutan gender, human gene, german gender
bias time » bias die, his time
das time » das tier, das tuke, his time
how has » how have

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: ((range planning) OR (land planning)) data human gender ((bias time) OR (das time)) how has ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((range planning) or (land planning)) data human gender ((bias time) OR (das time)) how has ;~".
• Adding a wildcard symbol may retrieve word variants: ((range planning) or (land planning)) data human gender ((bias time) OR (das time)) how has ;*.
