Assuming that you store the URLs untokenized you can use TermEnum like
below:
Lucene.Net.Index.IndexReader rdr = Lucene.Net.Index.IndexReader.Open(INDEX);
string field = "URL";
string prefix = "go";
Lucene.Net.Index.TermEnum tEnum = rdr.Terms( new
Lucene.Net.Index.Term(field,prefix) );
while(tEnum.Next())
{
if(! tEnum.Term().Text().StartsWith(prefix) ) break;
Console.WriteLine( tEnum.Term().Text() );
}

Subject: Search autocomplete/suggestion
I would like to implement automatic phrase suggestion as one type in the
searchfield. I have tried different Lucene.net quries without any luck.
The functionality I would like is simialr to the SQL Like % method.
For instance, if one types "g", "go", "goo", "goog"... I would like "
google.com" in the search result, but I don't want "docs.google.com".
My main problem is that Lucene.net is searching by terms and I can't figure
out how to force it to exclude "docs.google.com" from the results.
