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