Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"cua dat anh grippers" » "cua dan anh grippers", "cua vat anh grippers", "cua dai anh grippers", "cua sat anh grippers", "cua dat khanh grippers", "cua nhat anh grippers", "cua dat anh slippers"

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 dat anh grippers\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( cua dat anh grippers ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cua dat anh grippers") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
