Perhaps you should try some spelling variations:
"va using code snippets" » "va using cfd snippets", "va using one snippets", "va ung code snippets", "_ using code snippets", "19 using code snippets"
"using raw java snippets" » "using real java snippets", "using a java snippets", "using low java snippets"
"locating bug core snippets" » "locating bug 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: "((((\"va using code snippets\") OR (\"using raw java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( va using code snippets ) OR ( using raw java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("va using code snippets") OR ("using raw java snippets"))) OR ("locating bug core snippets"))*.
