# Filters

For example, a user can filter the Explore's query results to the last three months for a blockchain, or for a specific wallet address. Users can also limit the number of rows that are displayed in an "Explore" or the number of pivot columns that are displayed. 

### Filtering Data

Filters let you restrict the data that you are viewing to items of interest. Any field in your ChainArgos instance can become a filter.

You also don't need to add a "DIMENSION" or "MEASURE"  to your results to filter on it. 

For example, you can create a query that filters the "From Address" to the last three months, even though your results only show "Amount" and "Sum of Transfer Amounts."

You can use a **combination** of these filters in your query:

* **Basic Filters** are the most commonly used, and ChainArgos provides appropriate drop-down lists, widgets, and text fields. 
* **Advanced Filters** are highly customizable and allow user-configured specific values known as "user attributes" that allow a user to automatically customize a Look for each individual user (optional). Contact your system administrator if you would like to customize Advanced Filters for specific users in your workgroup.   
* **Custom Filters** let you write the fields, constants, functions, and operators for your desired filtering. ChainArgos lets you build an expression that evaluates as `TRUE` or `FALSE`. When you run the query, ChainArgos only returns rows for which that condition is `TRUE`.
