# Use the Search API
The Search API exposes services which allow you to create and manage search [authentication](https://docs.coveo.com/en/2120/) providers and [query pipelines](https://docs.coveo.com/en/180/).
Most importantly, the Search API allows you to perform [queries](https://docs.coveo.com/en/231/) on an [index](https://docs.coveo.com/en/204/).

Search pages based on the [Coveo JavaScript Search Framework](https://docs.coveo.com/en/187/) are powered by the Search API.

> **Notes**
>
> * Search integrations with the [Coveo Platform](https://docs.coveo.com/en/186/) typically rely on the [JavaScript Search Framework](https://docs.coveo.com/en/187/) rather than directly on the Search API (and other APIs).
>  
> If, for some legitimate reason, you can't use the [JavaScript Search Framework](https://docs.coveo.com/en/187/) in your custom search integration with the [Coveo Platform](https://docs.coveo.com/en/186/), see [Use the REST APIs to build a search UI](https://docs.coveo.com/en/1370/).

> All REST API string fields are case-sensitive unless otherwise specified.
> For example, [search queries aren't case-sensitive](https://docs.coveo.com/en/3074/).
> 
> To keep behavior consistent across the [Coveo Platform](https://docs.coveo.com/en/186/), the same value passed to different REST APIs must always be passed using the same case.
> For example, if the [unique product identifier](https://docs.coveo.com/en/n73f0502#define-a-unique-product-identifier), such as `ec_product_id`, is passed to the Commerce API in lowercase, then it should also be passed to the Usage Analytics Write API in lowercase.

In the [Coveo Administration Console](https://docs.coveo.com/en/183/), the [**Content Browser**](https://platform.cloud.coveo.com/admin/#/orgid/content/browser/) ([platform-ca](https://platform-ca.cloud.coveo.com/admin/#/orgid/content/browser/) | [platform-eu](https://platform-eu.cloud.coveo.com/admin/#/orgid/content/browser/) | [platform-au](https://platform-au.cloud.coveo.com/admin/#/orgid/content/browser/)) page, and all the pages under the **Search** section use the Search API extensively (see [Tune relevance](https://docs.coveo.com/en/3371/)).
