Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"moi do danh snippets" » "moi do dinh snippets", "moi do sanh snippets", "moi dia danh snippets", "moi doi danh snippets", "moi co danh snippets", "moi de danh snippets", "moi do danh 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 (\"moi do danh snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( moi do danh snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("moi do danh snippets"))) OR ("locating bug code snippets"))*.
