Client APIs This section discusses the available client APIs for Solr. It covers the following topics: Introduction to Client APIs: A conceptual overview of Solr client APIs. Choosing an Output Format: Information about choosing a response format in Solr. Using JavaScript: Explains why a client API is not needed for JavaScript responses. Using Python: Information about Python and JSON responses. Client API Lineup: A list of all Solr Client APIs, with links. Using SolrJ: Detailed information about SolrJ, an API for working with Java applications. Using Solr From Ruby: Detailed information about using Solr with Ruby applications. MBean Request Handler: Describes the MBean request handler for programmatic access to Solr server statistics and information. Introduction to Client APIs At its heart, Solr is a Web application, but because it is built on open protocols, any type of client application can use Solr. HTTP is the fundamental protocol used between client applications and Solr. The client makes a request and Solr does some work and provides a response. Clients use requests to ask Solr to do things like perform queries or index documents. Client applications can reach Solr by creating HTTP requests and parsing the HTTP responses. Client APIs encapsulate much of the work of sending requests and parsing responses, which makes it much easier to write client applications. Clients use Solr's five fundamental operations to work with Solr. The operations are query, index, delete, commit, and optimize. Queries are executed by creating a URL that contains all the query parameters. Solr examines the request URL, performs the query, and returns the results. The other operations are similar, although in certain cases the HTTP request is a POST operation and contains information beyond whatever is included in the request URL. An index operation, for example, may contain a document in the body of the request. Solr also features an EmbeddedSolrServer that offers a Java API without requiring an HTTP connection. For details, see Using SolrJ. 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. Client API Lineup Apache Solr Reference Guide 6.0 640
The Solr Wiki contains a list of client APIs at http://wiki.apache.org/solr/IntegratingSolr.

In fact, it is so straightforward that there is no client API. You don't need to install any packages or configure anything. HTTP requests can be sent to Solr using the standard XMLHttpRequest mechanism. Out of the box, Solr can send JavaScript Object Notation (JSON) responses, which are easily interpreted in JavaScript. Just add wt=json to the request URL to have responses sent as JSON. For more information and an excellent example, read the SolJSON page on the Solr Wiki: http://wiki.apache.org/solr/SolJSON Using Python Solr includes an output format specifically for Python, but JSON output is a little more robust. Simple Python Making a query is a simple matter. First, tell Python you will need to make HTTP connections. Apache Solr Reference Guide 6.0 641
