Question

I was wondering how I can enable faceting in the solr config without being forced to put it all the times in the URL. Secondly how can set the number of fields?
thanks

You can pass all the default parameters you need to your request handler like this:

<requestHandler name="standard" class="solr.SearchHandler" default="true">
    <lst name="defaults">
        <str name="facet">true</str>
        <str name="facet.field">field1</str>
        <str name="facet.field">field2</str>
        <str name="facet.field">field3</str>
   </lst>        
</requestHandler>

This way you have facet enabled by default for field1, field2 and field3.
