Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"mong doi su snippets" » "vong doi su snippets", "dong doi su snippets", "mong do su snippets", "mong oi su snippets", "mong don su snippets", "mong voi su snippets", "mong doi su 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 java snippets\") OR (\"mong doi su snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( mong doi su snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("mong doi su snippets"))) OR ("locating bug code snippets"))*.
