Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"nan dan van snippets" » "nhan dan van snippets", "nang dan van snippets", "ban dan van snippets", "nan dang van snippets", "nan doan van snippets", "nan dao van snippets", "nan dan 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: "((((\"nan dan van snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( nan dan van snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("nan dan van snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
