Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"doc 2 robot snippets" » "doc _ robot snippets", "doc a robot snippets", "doc _ robots snippets", "doc 1 robot snippets", "doc 3 robot snippets", "doc 4 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 (\"doc 2 robot snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( doc 2 robot snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("doc 2 robot snippets"))) OR ("locating bug core snippets"))*.
