Perhaps you should try some spelling variations:
python modelo » python module (Expand search), python morelia (Expand search), python code (Expand search)
modelo lambda » modelo lagoa (Expand search), modelo lda (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)
decrease std » decrease sod (Expand search), decrease and (Expand search), decrease at (Expand search)
std programa » sd programa (Expand search), bad programa (Expand search), cad programa (Expand search)

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

• Removing quotes may allow a broader search: (( decrease toc decrease std programa ) OR ( python modelo lambda python programming ))~.
