I want output to be in csv when I query SOLR , but output still comes in javabin

问题

SolrQuery query = new SolrQuery();
query.setQuery("*:*");
query.add("wt","csv");
server.query(query);

In QueryResponse object params come out to be params{q=:,wt=javabin,version=2}

Even though I have set wt as csv in code above . Any way how to get solr output in csv ?

回答1:

The solrj Java library only supports javabin and xml.

You can use HttpSolrServer#setParser(ResponseParser processor) to define the format. The wt parameter won't work here.

If you want a csv output you have to manually transform the response from Solr to the csv format.
