Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"cho cho can snippets" » "choi cho can snippets", "cao cho can snippets", "cho chu can snippets", "cho cho cac snippets", "cho cho phan snippets", "cho cho cong snippets"
"locating bug code snippets" » "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: "((((\"python using java snippets\") OR (\"cho cho can snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( cho cho can snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("cho cho can snippets"))) OR ("locating bug code snippets"))*.
