[jsui-new Coveo JavaScript Search Framework v2.4094.8]


The JavaScript Relevance Inspector presents centralized information about your search component.
This includes ranking information for each result, its available metadata and fields, and an execution report for the performed query.

The Relevance Inspector is meant to be used by developers and administrators to understand how their search page behaves to either fine-tune their relevance or troubleshoot issues during development.

## Accessing the Relevance Inspector

. Ensure that you're using the [May 2018 release (v2.4094.8)](https://docs.coveo.com/en/410#may-2018-release-v240948) version, or a subsequent version of the Coveo JavaScript Search Framework (see [Identifying the JavaScript Search Version](https://docs.coveo.com/en/327/)).
. Access the page where your search component is.
. In the URL of that page, add the `debug=true` option.
This is either expressed as `#debug=true` if it's the only option, or `&debug=true` if you have other options.


**Example**

The url of your search page is `+https://www.example.com/search/+`.

To access the debug mode, you would need to access the `+https://www.example.com/search/#debug=true+` URL.
. Once you have accessed the debug mode of your search page, you should already see more information about the score of your search result.
You should also see a link to the Relevance Inspector at the top of the page.

To access the relevance inspector, click **Relevance Inspector** at the top of the page.



## About the Relevance Inspector

The Relevance Inspector is divided into four sections, each providing specific information about your search page.

### Ranking information

This section presents your results with their associated score.

It's meant to be used by integrators to know why results are shown in a specific order.

### Metadata

This section presents the available fields and field values available for each result.

It's meant to be used during development, to know what field values are available to be used in your [result templates](https://docs.coveo.com/en/413/).

### Execution report

This section presents various information about your query.

This includes information about authentication, the pipeline used for your query and its effect on the query, the different ranking modifiers and Machine Learning boosts, and the complete query sent to the index.

### Available fields

This section provides information about all the fields available for your search page.
This includes the description of each field as well as the field options.
