Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"tri hoc ban snippets" » "triet hoc ban snippets", "tri thuc ban snippets", "thai hoc ban snippets", "tri hoc bang snippets", "tri hoc dan snippets", "tri hoc bai snippets", "tri hoc ban 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: "((((\"tri hoc ban snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( tri hoc ban snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("tri hoc ban snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
