Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets"
"oi quoc ban snippets" » "oi quoc bao snippets", "oi quoc lan snippets", "oi quoc quan snippets", "voi quoc ban snippets", "si quoc ban snippets", "mai quoc ban snippets"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("oi quoc ban snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"oi quoc ban snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))*".
• Removing quotes may allow a broader search: (((( oi quoc ban snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))*.
