Perhaps you should try some spelling variations:
"locating bug code slippers" » "locating bug code snippets", "locating bung code slippers", "locating bugs code slippers"
"python using java slippery" » "python using data slippery"
"n trinh han snippets" » "n trinh quan snippets", "p trinh han snippets", "anh trinh han snippets", "dan trinh han 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: "((((\"n trinh han snippets\") OR (\"python using java slippery\"))) OR (\"locating bug code slippers\"))~".
• Removing quotes may allow a broader search: (((( n trinh han snippets ) OR ( python using java slippery ))) OR ( locating bug code slippers ))~.
• Adding a wildcard symbol may retrieve word variants: (((("n trinh han snippets") OR ("python using java slippery"))) OR ("locating bug code slippers"))*.
