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