Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"anh ve da snippets" » "hanh ve da snippets", "anh va da snippets", "anh viet da snippets", "anh ve dao snippets", "anh ve dat snippets", "anh ve dan 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: "((((\"anh ve da snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( anh ve da snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("anh ve da snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
