Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"phi van lua snippets" » "phi san lua snippets", "thi van lua snippets", "phi va lua snippets", "phi van luan snippets", "phi van lu snippets", "phi van luc 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: "((((\"python using java snippets\") OR (\"phi van lua snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( phi van lua snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("phi van lua snippets"))) OR ("locating bug core snippets"))*.
