Perhaps you should try some spelling variations:
"creating a tre snippets" » "creating _ tre snippets", "reading a tre snippets", "creating va tre snippets", "creating o tre snippets"
"creating a pre snippets" » "creating _ pre snippets", "reading a pre 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.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("creating a tre snippets") OR ("creating a pre snippets"))) or ("locating bug code snippets"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("creating a tre snippets") OR ("creating a pre snippets"))) OR ("locating bug code snippets"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"creating a tre snippets\") OR (\"creating a pre snippets\"))) or (\"locating bug code snippets\"))*".
• Removing quotes may allow a broader search: (((( creating a tre snippets ) OR ( creating a pre snippets ))) or ( locating bug code snippets ))*.
