Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets", "using java core snippets"
"ban a chi snippets" » "ban va chi snippets", "ban ma chi snippets", "ban da chi snippets", "ban _ chi snippets", "ban y chi snippets"
"locating bug code snippets" » "locating bug core snippets", "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: "((((\"using java code snippets\") OR (\"ban a chi snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( ban a chi snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("ban a chi snippets"))) OR ("locating bug code snippets"))*.
