Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"hieu bo ben snippets" » "hieu so ben snippets", "thieu so ben snippets", "hieu bo bien snippets", "hieu bo benh snippets", "hieu do ben 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: "((((\"hieu bo ben snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( hieu bo ben snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("hieu bo ben snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
