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