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