Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"pham ap dat snippets" » "pham gap dat snippets", "pham phap dat snippets", "pham van dat snippets", "pham lap dat snippets", "pham chap dat 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 ap dat snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( pham ap dat snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("pham ap dat snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
