Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"l doc cua snippets" » "l hoc cua snippets", "l doi cua snippets", "l do cua snippets", "l dos cua snippets", "l moc cua snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code snippets", "locating bug core 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: "((((\"l doc cua snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( l doc cua snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("l doc cua snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
