Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"tri moi vao snippets" » "tri mot vao snippets", "thi moi vao snippets", "tri doi vao snippets", "tri moi va snippets", "tri moi van snippets", "tri moi giao 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: "((((\"python using java snippets\") OR (\"tri moi vao snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( tri moi vao snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("tri moi vao snippets"))) OR ("locating bug core snippets"))*.
