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