Perhaps you should try some spelling variations:
"python using real snippets" » "python using metal snippets", "python using raw snippets"
"pha hoc code snippets" » "pha hoc co snippets", "pha hoc cong snippets", "pha hoc de snippets", "phap hoc code snippets", "phau hoc code snippets", "nha hoc code snippets"
"locating bug core snippets" » "locating bug code snippets"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("pha hoc code snippets") OR ("python using real snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"pha hoc code snippets\") OR (\"python using real snippets\"))) OR (\"locating bug core snippets\"))".
• Removing quotes may allow a broader search: (((( pha hoc code snippets ) OR ( python using real snippets ))) OR ( locating bug core snippets )).
• Adding a wildcard symbol may retrieve word variants: (((("pha hoc code snippets") OR ("python using real snippets"))) OR ("locating bug core snippets"))*.
