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