Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"chu va danh snippets" » "chu va dinh snippets", "chu va dan snippets", "chu va hanh snippets", "chu van danh snippets", "chuc va danh snippets", "chua va danh snippets", "chu va 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: "((((\"chu va danh snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( chu va danh snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("chu va danh snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
