Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"do thoi duc snippets" » "do tho duc snippets", "do thoi dai snippets", "do thi dua snippets", "dao thoi duc snippets", "doi thoi duc snippets", "do thi duc snippets", "do thoi duc 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: "((((\"do thoi duc snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( do thoi duc snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("do thoi duc snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
