Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"khoi can vi snippets" » "khoa can vi snippets", "khoi nang vi snippets", "hoc can vi snippets", "khoi gan vi snippets", "khoi ban vi snippets", "khoi can va snippets", "khoi can vi 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: "((((\"khoi can vi snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( khoi can vi snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("khoi can vi snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
