Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"chu van tin snippets" » "cuu van tin snippets", "chu han tin snippets", "chu van tien snippets", "chu van tan snippets", "chu van thinh 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: "((((\"chu van tin snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( chu van tin snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("chu van tin snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
