Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"doi dan xac snippets" » "hoi dan xac snippets", "doi ban xac snippets", "doi dau xac snippets", "doi dan bac snippets", "doi dan cac snippets", "doi dan xa snippets", "doi dan xac 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: "((((\"doi dan xac snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( doi dan xac snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("doi dan xac snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
