Perhaps you should try some spelling variations:
"python using code snippets" » "python using cfd snippets", "python using one snippets"
"locating bug core snippets" » "locating bug code snippets"
"tri nhi van snippets" » "tri nho van snippets", "tri noi van snippets", "tri chi van snippets", "tri nhin van snippets", "tri thi van snippets", "tri nha 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 code snippets\") OR (\"tri nhi van snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using code snippets ) OR ( tri nhi van snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using code snippets") OR ("tri nhi van snippets"))) OR ("locating bug core snippets"))*.
