• If you are trying to use Boolean operators, they must be ALL CAPS: (((("reading 2 code snippets") OR ("reading 3 code snippets"))) OR ("locating bug code snippets")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"reading 2 code snippets\") OR (\"reading 3 code snippets\"))) or (\"locating bug code snippets\"))".
• Removing quotes may allow a broader search: (((( reading 2 code snippets ) OR ( reading 3 code snippets ))) or ( locating bug code snippets )).
• Adding a wildcard symbol may retrieve word variants: (((("reading 2 code snippets") OR ("reading 3 code snippets"))) or ("locating bug code snippets"))*.
