Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"thi ca dung snippets" » "thi cap dung snippets", "thi cu dung snippets", "thi ca nung snippets", "thi cam dung snippets", "thi cua dung snippets", "thi cai 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: "((((\"python using java snippets\") OR (\"thi ca dung snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( thi ca dung snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("thi ca dung snippets"))) OR ("locating bug core snippets"))*.
