Answer 1

Your question is tagged with Lucene.NET so I assume you mean the .NET version rather than the Java version.

Yes, you can have wildcards at the beginning of a search term by via

var queryParser = new QueryParser(LuceneVersion, "content", new StandardAnalyzer(LuceneVersion));
queryParser.SetAllowLeadingWildcard(true);

but you need to be aware of the performance consequences. Find more detailed source code in this blog.

Since Lucene.NET is a port of the Java version, I suspect you could use the same approach for the Java version. I didn't verify this, though.
