Perhaps you should try some spelling variations:
"creating vq doi snippets" » "creating _ doi snippets", "creating a doi snippets", "creating va doi snippets", "creating ve doi snippets", "creating tvqg doi snippets"
"reading 1 doc snippets" » "reading _ doc snippets", "reading 2 doc snippets", "reading 3 doc snippets", "reading n1 doc 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 vq doi snippets\") OR (\"reading 1 doc snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( creating vq doi snippets ) OR ( reading 1 doc snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("creating vq doi snippets") OR ("reading 1 doc snippets"))) OR ("locating bug code snippets"))*.
