Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"missing java java snippets" » "missing data java snippets", "using java java snippets"
"gia cong va snippets" » "cua cong va snippets", "va cong va snippets", "gia dong va snippets", "gia cong ha snippets", "gia cong tac 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: "((((\"missing java java snippets\") OR (\"gia cong va snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( missing java java snippets ) OR ( gia cong va snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("missing java java snippets") OR ("gia cong va snippets"))) OR ("locating bug core snippets"))*.
