Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"son te dung snippets" » "son tieu dung snippets", "son tien dung snippets", "son tin dung snippets", "son le dung snippets", "son tp dung snippets", "son ve dung snippets", "son te dung 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: "((((\"son te dung snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( son te dung snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("son te dung snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
