Perhaps you should try some spelling variations:

decreases their » decrease their (Expand search), decreases the (Expand search), increases their (Expand search)
decrease cells » decrease cell (Expand search), decreases cell (Expand search), decrease costs (Expand search)

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

• Removing quotes may allow a broader search: (( decrease cells decreases their programming ) OR ( python using pid python programming ))~.
