"using 3d code snippets" » "using 3 code snippets", "using a code snippets", "using _ code snippets", "using cfd code snippets"
"locating bug core snippets" » "locating bug code snippets"

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"using 3d code snippets\") OR (\"dang using java snippets\"))) OR (\"locating bug core snippets\"))".
• Removing quotes may allow a broader search: (((( using 3d code snippets ) OR ( dang using java snippets ))) OR ( locating bug core snippets )).
• Adding a wildcard symbol may retrieve word variants: (((("using 3d code snippets") OR ("dang using java snippets"))) OR ("locating bug core snippets"))*.
