Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"doi han ap snippets" » "doi nhan ap snippets", "doi hanh ap snippets", "dai han ap snippets", "doi han tap snippets", "doi khan ap snippets", "doi dan ap snippets", "doi han ap 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 han ap snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( doi han ap snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("doi han ap snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
