Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"su can nha snippets" » "su cac nha snippets", "su ban nha snippets", "su cau nha snippets", "su van nha snippets", "su cao nha snippets", "su han nha snippets", "su can nha 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: "((((\"su can nha snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( su can nha snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("su can nha snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
