Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"hoa phan xa snippets" » "hoa dan xa snippets", "co phan xa snippets", "hoa phan xay snippets", "hoa phan ba snippets", "hoa phan ha 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: "((((\"hoa phan xa snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( hoa phan xa snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("hoa phan xa snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
