Perhaps you should try some spelling variations:
their programming » their reprogramming (Expand search), theory programming (Expand search), the programming (Expand search)
decrease their » decrease the (Expand search), increase their (Expand search), decreases the (Expand search)
photon python » piton python (Expand search), photon photon (Expand search), pitons python (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (Expand search)

using photon » using proton (Expand search), using photo (Expand search), using diphoton (Expand search)

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

• Removing quotes may allow a broader search: (( decrease and decrease their programming ) OR ( action using photon python programming ))~.
