Perhaps you should try some spelling variations:
"doi dan mong snippets" » "doi dan code snippets", "doi dan dong snippets", "doi dan mon snippets", "doi dan ong snippets", "hoi dan mong snippets", "doi ban mong snippets", "doi dau mong snippets"
"locating bug core snippets" » "locating bug code 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: "((((\"python using java snippets\") OR (\"doi dan mong snippets\"))) OR (\"locating bug core snippets\"))".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( doi dan mong snippets ))) OR ( locating bug core snippets )).
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("doi dan mong snippets"))) OR ("locating bug core snippets"))*.
