Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"phap hoc 3 snippets" » "phap hoan 3 snippets", "phap mo 3 snippets", "phap han 3 snippets", "phap hoc y snippets", "phap hoc _ snippets", "phap hoc o snippets"
"python using a slippers" » "python using a slippery", "python using a grippers"

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 a slippers\") OR (\"phap hoc 3 snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using a slippers ) OR ( phap hoc 3 snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using a slippers") OR ("phap hoc 3 snippets"))) OR ("locating bugs code snippets"))*.
