How can I get NHibernate.Search FT query to use a “free text” query style?

Question

I'm trying to implement a text search option using the Lucene-based full-text search engine on my NHibernate-based MVC project (NHibernate.Search). All the documentation I've seen on how to do this suggests I need to look at specific columns for values, something like:

            var query = "Title:Ford";
            using (var search = NHibernate.Search.Search.CreateFullTextSession(s))
            {                   
                using (var transaction = s.BeginTransaction())
                {
                    var carSearchResults = search.CreateFullTextQuery(query)
                        .SetMaxResults(5)
                        .List();  
                    foreach(var car in carSearchResults)
                    {
                        Console.WriteLine(car.Title);
                    }
                    transaction.Commit();
                }
            }

I would rather look at all full-text indexed columns for the search string, like you can do in SQL with a wildcard on the FREETEXT function... so I could do something like:

            var query = "Ford";
            using (var search = NHibernate.Search.Search.CreateFullTextSession(s))
            {                   
                using (var transaction = s.BeginTransaction())
                {
                    var carSearchResults = search.CreateFullTextQuery(query)
                        .SetMaxResults(5)
                        .List();  
                    foreach(var car in carSearchResults)
                    {
                        Console.WriteLine(car.Title);
                    }
                    transaction.Commit();
                }
            }

... and this would examine all full-text indexed properties for "Ford", and return all hits. Is there a comparable function/ method/ syntax for this using the NHibernate-based search engine?

Take a look at How to incorporate multiple fields in QueryParser?

Short answer, change:

var query = "Title:Ford";

to:

var query = "Title:Ford OR Name:Ford OR Field1:Ford OR Field2:Ford"; // etc for all fields
