limit on number of values in a filter query?

[Phillip Farber]

I use a filter query (fq) parameter in my requests to limit the select 
response to a subset of all document ids.  I'm getting a Solr exception 
when the number of values in the fq approaches 1000.   I get the 
following response from Solr:

_header=[6518349,32231686,m=4,g=4096,p=4096,c=4096]={/solr/select?q=ship&fl=id,score&fq=id:(883108+1355308+
... <<several 100's of ids>> ... +851832976+8536687}{}
_buffer=[6518349,32231686,m=4,g=4096,p=4096,c=4096]={/solr/select?q=ship&fl=id,score&fq=id:(883108+1355308+
... <<several 100's of ids>> ... +851832976+8536687}{}

The id field is currently a string.  Would it help to make it a long 
int? Is there some internal limit on the number of values in a fq or is 
there a configuration parameter that will allow me to increase this number?

Thanks,

Phil
