I want to read one the parameters (maxBooleanClauses) specified in the solrconfig.xml at the client side. I tried to check if there is any API to do that, but didn't find any. Can someone please help?
While there is not currently a way to get individual settings for the options in the solrconfig.xml file like there is for the schema (via Schema REST API). You can configure Solr to make the entire solrconfig.xml file "gettable" via The Admin/GUI Section settings. This would allow you to retrieve the file and parse it to determine the value of the maxBooleanClauses setting.
