Perhaps you should try some spelling variations:
"creating a core snippets" » "creating _ core snippets", "creating a care snippets", "creating a corn snippets", "creating a c1ore snippets", "creating a coore snippets", "creating va core snippets"
"reading a c snippets" » "reading _ c snippets", "reading 1 c snippets", "reading 2 c snippets", "reading a c1 snippets", "reading a co snippets", "reading va c 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"creating a core snippets\") OR (\"reading a c snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( creating a core snippets ) OR ( reading a c snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("creating a core snippets") OR ("reading a c snippets"))) OR ("locating bug code snippets"))*.
