Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"dung mo lan snippets" » "dung co lan snippets", "dung cho lan snippets", "dung von lan snippets", "dung mot lan snippets", "dung mo ban snippets", "dung mo lay snippets", "dung mo 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: "((((\"dung mo lan snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( dung mo lan snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dung mo lan snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
