Perhaps you should try some spelling variations:
"creating a mem snippets" » "creating _ mem snippets", "creating a mem slippers"
"reading a sem snippets" » "reading _ sem snippets", "reading 1 sem snippets", "reading 2 sem snippets", "reading a set snippets", "reading a sem slippers"
"locating bug code snippets" » "locating bug code slippers", "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 mem snippets\") OR (\"reading a sem snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( creating a mem snippets ) OR ( reading a sem snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("creating a mem snippets") OR ("reading a sem snippets"))) OR ("locating bug code snippets"))*.
