Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets"
"tri moi da snippets" » "tri mot da snippets", "thi moi da snippets", "tri doi da snippets", "tri moi dan snippets", "tri moi la snippets", "tri moi va 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 (\"tri moi da snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using data snippets ) OR ( tri moi da snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using data snippets") OR ("tri moi da snippets"))) OR ("locating bugs code snippets"))*.
