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