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