### Overview

The data catalog is on the **[Browse]($PLATFORM_HOSTNAME)** page of your Databento portal.
In addition, you can browse datasets from different exchanges, like CME and Nasdaq. Each dataset
consists of products (read more about the definition of a product
[here](https://databento.com/docs/faqs/instruments-and-products.md)).

### Searching for products
You can also search for products on the **[Browse]($PLATFORM_HOSTNAME)** page by typing directly
into the search bar. You can filter your results based on the following:

- **Asset class.** Search within equities, FX, futures, and options.
- **Category**. Search within raw market data, reference data, and textual data.
- **Schema.** Search within MBO, MBP, TBBO, Trades, and more. Learn more about our supported
              schemas [here](https://databento.com/docs/schemas.md).
- **Publisher.** Search within venues (such as CME Globex, Nasdaq, OPRA) and vendors
                 (for instance EDI).
- **Region.** Search within North America, Europe, and Asia.
- **Available history.** Search within ranges from one month to at least 3 years.

Clicking on a product in the results will take you to its [Instrument details page]($PLATFORM_HOSTNAME/portal/data-catalog#instrument-details-page)
