Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"cau a robot snippets" » "cau _ robot snippets", "cau tao robot snippets", "cau tay robot snippets", "chau a robot snippets", "cau ha robot snippets", "cau va robot 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: "((((\"python using java snippets\") OR (\"cau a robot snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( cau a robot snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("cau a robot snippets"))) OR ("locating bug core snippets"))*.
