Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"quy phi phi snippets" » "duy phi phi snippets", "quy thi phi snippets", "quy pham phi snippets", "quy chi phi snippets", "quy phi thi 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: "((((\"quy phi phi snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( quy phi phi snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("quy phi phi snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
