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