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