Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"hang ca thi snippets" » "hang va thi snippets", "nang cao thi snippets", "hang tai thi snippets", "hang cau thi snippets", "hang can thi snippets", "hang cao thi snippets", "hang ca thi 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 (\"hang ca thi snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( hang ca thi snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("hang ca thi snippets"))) OR ("locating bug code snippets"))*.
