Perhaps you should try some spelling variations:
coder functions » power functions (Expand search), order functions (Expand search), colour functions (Expand search)
and extraction » fluid extraction (Expand search)
functions and » function and (Expand search), functional and (Expand search)
usando codigo » usando codigos (Expand search), jusante codigo (Expand search)
python python » pythons python (Expand search), piton python (Expand search), pitons python (Expand search)

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: (( coder functions AND extraction methods ) OR ( usando codigo python python programming ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( coder functions and extraction methods ) OR ( usando codigo python python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( coder functions and extraction methods ) OR ( usando codigo python python programming ))*.
