Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"cho tinh su snippets" » "cho sinh su snippets", "cho minh su snippets", "tho tinh su snippets", "cho trinh su snippets", "cho hinh su snippets", "cho tinh tu snippets", "cho tinh su 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: "((((\"cho tinh su snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( cho tinh su snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cho tinh su snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
