Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"de dong hoc snippets" » "de dong code snippets", "de dong co snippets", "de dong luc snippets", "den dong hoc snippets", "di dong hoc snippets", "de dang hoc snippets"
"python using java snippets" » "python using data 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: "((((\"de dong hoc snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( de dong hoc snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("de dong hoc snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
