Perhaps you should try some spelling variations:
"creating a code snippets" » "creating _ code snippets"
"reading a du snippets" » "reading _ du snippets", "reading 1 du snippets", "reading 2 du snippets", "reading va du snippets", "reading la du snippets", "reading a d snippets"
"locating bug core snippets" » "locating bug code 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 code snippets") OR ("reading a du snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"creating a code snippets\") OR (\"reading a du snippets\"))) OR (\"locating bug core snippets\"))".
• Removing quotes may allow a broader search: (((( creating a code snippets ) OR ( reading a du snippets ))) OR ( locating bug core snippets )).
• Adding a wildcard symbol may retrieve word variants: (((("creating a code snippets") OR ("reading a du snippets"))) OR ("locating bug core snippets"))*.
