Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"php va doi snippets" » "phap va doi snippets", "phap vat doi snippets", "phap van doi snippets", "php va dai snippets", "php va doc snippets", "php va do 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: "((((\"php va doi snippets\") OR (\"python using java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( php va doi snippets ) OR ( python using java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("php va doi snippets") OR ("python using java snippets"))) OR ("locating bugs code snippets"))*.
