Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"de tang php snippets" » "de tang phu snippets", "de bang php snippets", "de nang phap snippets", "le tang php snippets", "de dang php snippets", "do tang php snippets", "de tang php 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: "((((\"de tang php snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( de tang php snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("de tang php snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
