Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"cau van du snippets" » "cau van code snippets", "chau van du snippets", "cuu van du snippets", "cac van du snippets", "cau van duy snippets", "cau van dau snippets", "cau van de 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: "((((\"python using data snippets\") OR (\"cau van du snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using data snippets ) OR ( cau van du snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using data snippets") OR ("cau van du snippets"))) OR ("locating bug core snippets"))*.
