Perhaps you should try some spelling variations:
"reading 2 lua snippets" » "reading _ lua snippets", "reading 1 lua snippets", "reading 3 lua snippets", "reading 2 lua slippers"
"learning _ code snippets" » "learning _ code slippers"
"locating bug code snippets" » "locating bug code slippers", "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: "((((\"learning _ code snippets\") OR (\"reading 2 lua snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( learning _ code snippets ) OR ( reading 2 lua snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("learning _ code snippets") OR ("reading 2 lua snippets"))) OR ("locating bug code snippets"))*.
