Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"phi mo hinh snippets" » "phi moi hinh snippets", "thi mo hinh snippets", "chi mo hinh snippets", "phi mo chinh snippets", "phi mo dinh snippets", "phi mo minh snippets", "phi mo hinh 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: "((((\"phi mo hinh snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( phi mo hinh snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("phi mo hinh snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
