Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"using java java snippets" » "using data java snippets"
"anh tran java slippery" » "anh trinh java slippery", "anh tuan java slippery", "anh toan java slippery", "anh trac java slippery", "anh tran java slippers"

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: "((((\"anh tran java slippery\") OR (\"using java java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( anh tran java slippery ) OR ( using java java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("anh tran java slippery") OR ("using java java snippets"))) OR ("locating bug core snippets"))*.
