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