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