Perhaps you should try some spelling variations:
"creating a toc snippets" » "creating _ toc snippets", "reading a toc snippets", "creating a top snippets"
"creating o xa snippets" » "creating _ xa snippets", "creating o ha 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 a toc snippets\") OR (\"creating o xa snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( creating a toc snippets ) OR ( creating o xa snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("creating a toc snippets") OR ("creating o xa snippets"))) OR ("locating bug code snippets"))*.
