Perhaps you should try some spelling variations:
"lochating bug code snippets" » "locating bug code snippets", "lochating bug core snippets"
"python using java snippets" » "python using data snippets"
"hoc tan ca snippets" » "hoc dan ca snippets", "hoc tap ca snippets", "hoc tai ca snippets", "hoc tan cua snippets", "hoc tang ca 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: "((((\"hoc tan ca snippets\") OR (\"python using java snippets\"))) OR (\"lochating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( hoc tan ca snippets ) OR ( python using java snippets ))) OR ( lochating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("hoc tan ca snippets") OR ("python using java snippets"))) OR ("lochating bug code snippets"))*.
