Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets", "python using data slippers"
"hoa phan a snippets" » "hoa dan a snippets", "co phan a snippets", "hoa phan ba snippets", "hoa phan ha snippets", "hoa phan va snippets", "hoa phan a slippers"

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: "((((\"hoa phan a snippets\") OR (\"python using data snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( hoa phan a snippets ) OR ( python using data snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("hoa phan a snippets") OR ("python using data snippets"))) OR ("locating bugs code snippets"))*.
