Perhaps you should try some spelling variations:
"python using raw snippets" » "python using real snippets", "python using a snippets", "python using low snippets"
"locating bug core snippets" » "locating bug code snippets"
"thu tu code snippets" » "thu bug code snippets", "thu tuc code snippets", "tu tu code snippets", "thu thuy 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: (((("python using raw snippets") OR ("thu tu code snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"python using raw snippets\") OR (\"thu tu code snippets\"))) OR (\"locating bug core snippets\"))".
• Removing quotes may allow a broader search: (((( python using raw snippets ) OR ( thu tu code snippets ))) OR ( locating bug core snippets )).
• Adding a wildcard symbol may retrieve word variants: (((("python using raw snippets") OR ("thu tu code snippets"))) OR ("locating bug core snippets"))*.
