Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"pan li tinh snippets" » "pan vi tinh snippets", "pan bi tinh snippets", "pan li kinh snippets", "ban li tinh snippets", "dan li tinh snippets", "han li tinh snippets", "pan li tinh 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: "((((\"pan li tinh snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( pan li tinh snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("pan li tinh snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
