Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"wei pan lan snippets" » "wei tan lan snippets", "wei tang lan snippets", "wei fang lan snippets", "wei phan lan snippets", "wei ban lan snippets", "wei van lan snippets", "wei pan lan 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: "((((\"wei pan lan snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( wei pan lan snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("wei pan lan snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
