Perhaps you should try some spelling variations:
"reading a case snippets" » "reading _ case snippets", "reading 2 case snippets", "reading 3 case snippets"
"reading 1 case snippets" » "reading _ case snippets", "reading 2 case snippets", "reading 3 case snippets", "reading 19 cases snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code snippets", "locating bug core snippets"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("reading a case snippets") OR ("reading 1 case snippets"))) OR ("locating bug code snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"reading a case snippets\") OR (\"reading 1 case snippets\"))) or (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( reading a case snippets ) OR ( reading 1 case snippets ))) or ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("reading a case snippets") OR ("reading 1 case snippets"))) or ("locating bug code snippets"))*.
