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"
"phap thu 3 snippets" » "phap thuc 3 snippets", "phap tu 3 snippets", "phap che 3 snippets", "phap thu y snippets", "phap thu 5 snippets", "phap thu 6 snippets"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("phap thu 3 snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"phap thu 3 snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))*".
• Removing quotes may allow a broader search: (((( phap thu 3 snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))*.
