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 ra snippets" » "hoa dan ra snippets", "co phan ra snippets", "hoa phan ba snippets", "hoa phan ha snippets", "hoa phan va 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 ra snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( hoa phan ra snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("hoa phan ra snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
