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