Perhaps you should try some spelling variations:
"using java core snippets" » "using data core snippets"
"da lang phi snippets" » "da lang phu snippets", "da lang chai snippets", "da lang ha snippets", "dua lang phi snippets", "da nang phi snippets", "va lang phi 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 (\"da lang phi snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java core snippets ) OR ( da lang phi snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java core snippets") OR ("da lang phi snippets"))) OR ("locating bug code snippets"))*.
