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