Perhaps you should try some spelling variations:
"python using sat snippets" » "python using data snippets", "python using a snippets", "python using raw snippets", "python using sat slippers"
"hat dan sio2 snippets" » "hat bao sio2 snippets", "hat cao sio2 snippets", "hat dan so snippets", "hat van sio2 snippets", "mat dan sio2 snippets", "nhat danh sio2 snippets", "hat dan sio2 slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code snippets", "locating bug core snippets"

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: "((((\"hat dan sio2 snippets\") OR (\"python using sat snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( hat dan sio2 snippets ) OR ( python using sat snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("hat dan sio2 snippets") OR ("python using sat snippets"))) OR ("locating bug code snippets"))*.
