Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"lua cac tu snippets" » "luat cac tu snippets", "cua cac tu snippets", "qua cac tu snippets", "lua cac thu snippets", "lua cach tu snippets", "lua cac du 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: "((((\"lua cac tu snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( lua cac tu snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("lua cac tu snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
