Choosing an Output Format

Many programming environments are able to send HTTP requests and retrieve responses. Parsing the responses is a slightly more thorny problem. Fortunately, Solr makes it easy to choose an output format that will be easy to handle on the client side.

Specify a response format using the wt parameter in a query. The available response formats are documented in Response Writers.

Most client APIs hide this detail for you, so for many types of client applications, you won’t ever have to specify a wt parameter. In JavaScript, however, the interface to Solr is a little closer to the metal, so you will need to add this parameter yourself.
