Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"tu trac ban snippets" » "tu truc ban snippets", "tu tranh ban snippets", "tu thach ban snippets", "ty trach ban snippets", "tap trac ban 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: "((((\"tu trac ban snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( tu trac ban snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("tu trac ban snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
