Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"quan vu cua snippets" » "quan vu code snippets", "quan vi cua snippets", "quan su cua snippets", "quan va cua snippets", "quan hu cua snippets", "quan tu cua snippets"
"python using java snippets" » "python using data 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: "((((\"quan vu cua snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( quan vu cua snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("quan vu cua snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
