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