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