You can use the Query screen to submit a search query to a Solr collection and analyze the results.
In the example in the screenshot, a query has been submitted, and the screen shows the query results sent to the browser as JSON.
In this example, a query for genre:Fantasy was sent to a "films" collection. Defaults were used for all other options in the form, which are explained briefly in the table below, and covered in detail in later parts of this Guide.
The response is shown to the right of the form. Requests to Solr are simply HTTP requests, and the query submitted is shown in light type above the results; if you click on this it will open a new browser window with just this request and response (without the rest of the Solr Admin UI). The rest of the response is shown in JSON, which is the default output format.
The response has at least two sections, but may have several more depending on the options chosen. The two sections it always has are the responseHeader and the response. The responseHeader includes the status of the search (status), the processing time (QTime), and the parameters (params) that were used to process the query.
The response includes the documents that matched the query, in doc sub-sections. The fields return depend on the parameters of the query (and the defaults of the request handler used). The number of results is also included in this section.
This screen allows you to experiment with different query options, and inspect how your documents were indexed. The query parameters available on the form are some basic options that most users want to have available, but there are dozens more available which could be simply added to the basic request by hand (if opened in a browser). The following parameters are available:
Specifies the query handler for the request. If a query handler is not specified, Solr processes the response with the standard query handler.
The query event. See Searching for an explanation of this parameter.
Sorts the response to a query in either ascending or descending order based on the response’s score or another specified characteristic.
start is the offset into the query result starting at which documents should be returned. The default value is 0, meaning that the query should return results starting with the first document that matches. This field accepts the same syntax as the start query parameter, which is described in Searching. rows is the number of rows to return.
Defines the fields to return for each document. You can explicitly list the stored fields, functions, and doc transformers you want to have returned by separating them with either a comma or a space.
Specifies the Response Writer to be used to format the query response. Defaults to JSON if not specified.
Click this button to request that the Response Writer use indentation to make the responses more readable.
Click this button to augment the query response with debugging information, including "explain info" for each document returned. This debugging information is intended to be intelligible to the administrator or programmer.
