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 dat snippets" » "pham doi dat snippets", "pham mo dat snippets", "pham o dat snippets", "pham de dat snippets", "pham do dai snippets", "pham do dac 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 dat snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( pham do dat snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("pham do dat snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
