Perhaps you should try some spelling variations:
"reading 2 code snippets" » "reading _ code snippets", "reading 1 code snippets", "leading _ code snippets"
"reading 3 code snippets" » "reading _ code snippets", "reading 1 code snippets", "leading _ code snippets"
"locating bug core snippets" » "locating bug code 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 2 code snippets") OR ("reading 3 code snippets"))) OR ("locating bug core snippets"))~.
• Removing quotes may allow a broader search: (((( reading 2 code snippets ) or ( reading 3 code snippets ))) or ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("reading 2 code snippets") or ("reading 3 code snippets"))) or ("locating bug core snippets"))*.
