Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"khoa can ha snippets" » "khoa cam ha snippets", "khoa cap ha snippets", "khoi can ha snippets", "khoa can hai snippets", "khoa can nha snippets", "khoa van ha 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: "((((\"khoa can ha snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( khoa can ha snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("khoa can ha snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
