Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"doc cao tu snippets" » "hoc cao tu snippets", "do cao tu snippets", "doc dao tu snippets", "doc cao thu snippets", "doc co tu snippets", "doc cao su snippets", "doc cao tu 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: "((((\"doc cao tu snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( doc cao tu snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("doc cao tu snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
