Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"hoc doi sin snippets" » "hoc dai sin snippets", "hoc noi sin snippets", "hoc moi sin snippets", "hoc doi song snippets", "hoc doi dien snippets", "hoc hoi sinh snippets", "hoc doi sin 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: "((((\"hoc doi sin snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( hoc doi sin snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("hoc doi sin snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
