I almost added that you could create a subclass of the Lucene query parser, 
as Solr does, and add the aliasing that way. There might/should be field 
aliasing code in Solr that you could easily apply in Solr. There really 
isn't a great reason why aliasing is only available in Solr and not in 
Lucene.

But unless you are prepared to hack on the query parser, alias support isn't 
available in Lucene right now.

Hi Jack

Thank you for your help.
My problem is, I have only a Lucene setup and can not switch to Solr : (

Cheers

With edismax in Solr 3.6/4.0 field aliases are supported:

"The syntax for aliasing is f.myalias.qf=realfield. A user query for 
myalias:foo will be queried as realfield:foo."

See:

Subject: How to use/create an alias to a field?

Hello

I am using Lucene 3.4 and I have nearly the same question like Jan in his 
post:
http://mail-archives.apache.org/mod_mbox/lucene-java-user/200801.mbox/%3C4791E482.60900%40gmx.de%3E


I could found something helpful in "Lucene in Action" or in the web.
What is the recommended way to create an alias to a field?
I want be able to use in the searchquery "au:some_name" or "auth:some_name" 
or "author:some_name", all using the field "author".

Many thanks in advance for any help or recommendations
Willi : )
