Perhaps you should try some spelling variations:
"data using java snippets" » "data using data snippets", "data using java slippers"
"hung chu code snippets" » "nhung chu code snippets", "hung thu code snippets", "chung chou code snippets", "hung chu de snippets", "hung cfd code snippets", "hung chu code slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code 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: "((((\"hung chu code snippets\") OR (\"data using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( hung chu code snippets ) OR ( data using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("hung chu code snippets") OR ("data using java snippets"))) OR ("locating bug code snippets"))*.
