Perhaps you should try some spelling variations:
"creating a sem snippets" » "creating _ sem snippets", "reading a sem snippets", "creating a set snippets"
"creating a sem slippers" » "creating _ sem slippers", "reading a sem slippers", "creating a set slippers", "creating a sem slippery", "creating a sem grippers"
"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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("creating a sem snippets") OR ("creating a sem slippers"))) OR ("locating bug code snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"creating a sem snippets\") OR (\"creating a sem slippers\"))) or (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( creating a sem snippets ) OR ( creating a sem slippers ))) or ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("creating a sem snippets") OR ("creating a sem slippers"))) or ("locating bug code snippets"))*.
