Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"data a dung snippets" » "data _ dung snippets", "data 4 dung snippets", "data ap dung snippets", "data va dung snippets", "data am dung 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: "((((\"data a dung snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( data a dung snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("data a dung snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
