Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"thi toan ho snippets" » "thi toan code snippets", "thi tran ho snippets", "thi hoan ho snippets", "thi loan ho snippets", "thi toan hoc snippets", "thi toan khoa snippets", "thi toan cao snippets"
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data 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: "((((\"thi toan ho snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( thi toan ho snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("thi toan ho snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))*.
