But how can I *store* a document with an URL as a field value ? E.g.
"domain_http://www.domain.com/?p=12345";
The "term query parser" may be able to *retrieve* field values with an ":", but
my current problem is that I can't store value with ":" with *Solrj*, the Java
library to communicate with Solr.
