Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"hoc can tu snippets" » "hoc dan tu snippets", "hoc cao tu snippets", "hoc cac tu snippets", "hoc ban tu snippets", "hoc van tu snippets", "hoc han tu snippets", "hoc can tu 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: "((((\"hoc can tu snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( hoc can tu snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("hoc can tu snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
