Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets"
"nhat co van snippets" » "nhat cho van snippets", "nhat so van snippets", "chat co van snippets", "nhat cao van snippets", "nhat vo van 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 (\"nhat co van snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using data snippets ) OR ( nhat co van snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using data snippets") OR ("nhat co van snippets"))) OR ("locating bug core snippets"))*.
