Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"thi hai son snippets" » "thi hai code snippets", "thi mai son snippets", "thi hanh son snippets", "thi thai son snippets", "thi ha son snippets", "thi dai son 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: "((((\"thi hai son snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( thi hai son snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("thi hai son snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
