Setting Nested Filters

  • Updated

Sisu provides the ability to set nested filters when defining and iterating on your analysis or drilling down into a fact.

Using Nested Filters for Defining Custom Filters

When setting filters or defining groups to compare, you can use a combination of AND and OR filters (referred to as nested filters). 

For example, the following nested filters will return shirts that are either red or blue:



Using Nested Filters for Defining Group Comparison

Nested filters can be particularly useful when defining groups to compare in a Group Comparison Analysis.  

For example, the following settings will compare red t-shirts to red dress shirts or blouses:



Filtering Syntax

You can filter by:

  • a single condition
    (color = blue)
  • a set of OR conditions
    (color = blue OR color = red OR ...)
  • a set of AND conditions
    (color = blue AND color = red AND ...)
  • sets of single or OR conditions joined by ANDs
    ((color = blue OR color = red) AND (style = shirt) AND ...)

Each condition can use the following relational operators:

  • Equal (=)
  • Not equal (≠)
  • Less than (<)
  • Less than or equal (≤)
  • Greater than (>)
  • Greater than or equal (≤)

Columns and values used in conditions are populated from the Metric's data source. Sisu users can also create a custom value.

Sisu conditions cannot currently compare against "empty value". If you would like to filter out empty values for a particular column, Sisu recommends defining a special character in your data source.

If when saving a filter or group comparison, Sisu shows an "Invalid filters" error:

  • Ensure any custom created values match the data type of their column. For example, "red" is not a valid value for a column with type "boolean".
  • Ensure all filters have a value.



If when saving a filter or group comparison, Sisu shows an "Error occurred while saving" error:

  • Ensure you have a valid network connection and try saving again.
