Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"mat dan liu snippets" » "hat dan liu snippets", "luat dan liu snippets", "mat bang liu snippets", "mat dan lieu snippets", "mat dan luu snippets", "mat dan li snippets", "mat dan liu 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: "((((\"mat dan liu snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( mat dan liu snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("mat dan liu snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
