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