Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"lua rai tu snippets" » "lua lai tu snippets", "luat dai tu snippets", "luan rui tu snippets", "lua tai tu snippets", "lua mai tu snippets", "lua cai tu 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: "((((\"lua rai tu snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( lua rai tu snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("lua rai tu snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
