Perhaps you should try some spelling variations:
"using java core snippets" » "using data core snippets"
"te think java snippets" » "te trinh java snippets", "te chinh java snippets", "te thi java snippets", "_ think java snippets"
"locating bug code 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 core snippets\") OR (\"te think java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java core snippets ) OR ( te think java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java core snippets") OR ("te think java snippets"))) OR ("locating bug code snippets"))*.
