Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"cua dan han snippets" » "cua dang han snippets", "cua ban han snippets", "ca dan han snippets", "cua dan chan snippets", "cua dan than snippets", "cua dan hanh 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: "((((\"cua dan han snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( cua dan han snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cua dan han snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
