Solr Facet标签排除不适用于空格

Question

I am using exclude and tag for faceting. Strange this is it works where I don't have space in value.

http://192.168.2.114:8983/solr/customer/select?indent=on&q=*:*&fq=(%7B!tag%3DstateName%7DstateName:%22Gujarat%22)&fq=(%7B!tag%3DstateName%7DstateName:%22AndhraPradesh%22)&facet=true&facet.limit=100&facet.mincount=0&facet.field=%7B!ex%3DstateName%7DcountryName&facet.field=%7B!ex%3DstateName%7DstateName&facet.field=%7B!ex%3DstateName%7Dicity&facet=true - This works

but

http://192.168.2.114:8983/solr/customer/select?indent=on&q=*:*&fq=(%7B!tag%3DstateName%7DstateName:%22Gujarat%22)&fq=(%7B!tag%3DstateName%7DstateName:%22Andhra Pradesh%22)&facet=true&facet.limit=100&facet.mincount=0&facet.field=%7B!ex%3DstateName%7DcountryName&facet.field=%7B!ex%3DstateName%7DstateName&facet.field=%7B!ex%3DstateName%7Dicity&facet=true - This does not

The only difference between these two is a space in {!tag=stateName}stateName="Andhra Pradesh" ( {!tag=stateName}stateName="AndhraPradesh" - this works).

I don't understand why. I have tried encoding the URL, ie put + or %20 for space, still no luck.

EDIT

Here is the definition of stateName field.

<field name="stateName" type="string" multiValued="false" indexed="true" stored="true"/>

<fieldType name="string" class="solr.StrField" sortMissingLast="true"/>

Problem is that local parameters in query must be at the beginning of the string:

{!tag=stateName}(stateName:"Andhra Pradesh")

and not

({!tag=stateName}stateName:"Andhra Pradesh")

You can also avoid parenthesis:

{!tag=stateName}stateName:"Andhra Pradesh"
