query matching issue

[Radha C.]

Hello list,
 
I have documents contains word "Richard Nass". I need to match the "Richard
Nass" documents for the query strings "richard", "nass", "rich".
The search works for the following query ,
 
http://localhost:8983/solr/select?q=author:Richard
<http://localhost:8983/solr/select?q=author:Richard nass> nass 
http://localhost:8983/solr/select?q=author:Richard
<http://localhost:8983/solr/select?q=author:Richard Nass> Nass
http://localhost:8983/solr/select?q=author:richard
<http://localhost:8983/solr/select?q=author:richard nass> nass
 
But doesnot work for q=author:Richard, q=author:nass q=author:rich...
 
I tried wildcard search like q=author:rich* also.
 
Can anyone help me how to get the flexible search as above.
 
Thanks in advance..
