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"
"cac tu cua snippets" » "cac thu cua snippets", "cach tu cua snippets", "cac du cua snippets", "cac hu cua snippets", "cac vu cua 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: "((((\"cac tu cua snippets\") OR (\"python using java snippets\"))) OR (\"lochating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( cac tu cua snippets ) OR ( python using java snippets ))) OR ( lochating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cac tu cua snippets") OR ("python using java snippets"))) OR ("lochating bug code snippets"))*.
