Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"dao voi can snippets" » "dao voi code snippets", "da voi can snippets", "dao noi can snippets", "do voi can snippets", "dao voi cac snippets", "dao voi cong snippets", "dao voi hang 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: "((((\"dao voi can snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( dao voi can snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dao voi can snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))*.
