Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"den ha hung snippets" » "den hai hung snippets", "den ham hung snippets", "den hao hung snippets", "den kha hung snippets", "den ho hung snippets", "den va hung snippets", "den ha hung 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 (\"den ha hung snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( den ha hung snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("den ha hung snippets"))) OR ("locating bug code snippets"))*.
