Perhaps you should try some spelling variations:
"creating a a snippets" » "creating _ a snippets", "reading a a snippets", "creating a a slippers"
"leading anh trac snippets" » "leading sinh trac snippets", "leading anh tuan snippets", "leading anh thuc snippets", "leading anh trac 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 a snippets\") OR (\"leading anh trac snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( creating a a snippets ) OR ( leading anh trac snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("creating a a snippets") OR ("leading anh trac snippets"))) OR ("locating bug code snippets"))*.
