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