Perhaps you should try some spelling variations:
"reading a code snippets" » "reading _ code snippets", "reading 1 code snippets", "reading 2 code snippets"
"reading a core snippets" » "reading _ core snippets", "reading 1 core snippets", "reading 2 core snippets", "reading a care snippets", "reading a corn 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 a code snippets") OR ("reading a core snippets"))) OR ("locating bug code snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"reading a code snippets\") OR (\"reading a core snippets\"))) or (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( reading a code snippets ) OR ( reading a core snippets ))) or ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("reading a code snippets") OR ("reading a core snippets"))) or ("locating bug code snippets"))*.
