Perhaps you should try some spelling variations:
pattern python » pattern action (Expand search), pattern method (Expand search)
decrease brain » decreased brain (Expand search), decreases brain (Expand search), decreases brown (Expand search)
python mapped » python based (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decrease on (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), not decrease (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease toc decrease brain abscess ) OR ( python mapped pattern python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease toc decrease brain abscess ) OR ( python mapped pattern python programming ))*.
