Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"dao dan chi snippets" » "dao van chi snippets", "cao dang chi snippets", "dao dong chi snippets", "dao danh chi snippets", "dao dan thi 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 (\"dao dan chi snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( dao dan chi snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("dao dan chi snippets"))) OR ("locating bug code snippets"))*.
