Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"python using java snippets" » "python using data snippets", "python using java slippers"
"f hoc phan snippets" » "f hoc dan snippets", "f hoc pho snippets", "y hoc phan snippets", "_ hoc phan snippets", "o hoc phan snippets", "f hoc phan slippers"

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: "((((\"f hoc phan snippets\") OR (\"python using java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( f hoc phan snippets ) OR ( python using java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("f hoc phan snippets") OR ("python using java snippets"))) OR ("locating bugs code snippets"))*.
