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