Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"len tinh tu snippets" » "yen tinh tu snippets", "den tinh tu snippets", "bien tinh tu snippets", "len trinh tu snippets", "len tinh thua snippets", "len tinh yeu 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: "((((\"len tinh tu snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( len tinh tu snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("len tinh tu snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
