Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"quan ho dua snippets" » "quan he dua snippets", "quan ha dua snippets", "quan so dua snippets", "quan hoc dua snippets", "quan ho duc snippets", "quan ho da 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 ho dua snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( quan ho dua snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("quan ho dua snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
