Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"pham do dao snippets" » "pham doi dao snippets", "pham mo dao snippets", "pham o dao snippets", "pham doc dao snippets", "pham de dao snippets", "pham do dai 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: "((((\"pham do dao snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( pham do dao snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("pham do dao snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
