[#8-8-0-sw-headline-aggregation]
[discrete]
=== Headline aggregation for discontinuous expressions

// Naomi

We changed the default behavior for table aggregation summaries when the search contains a formulas that contain both a conditional clause (`if... then... else`) and a group_aggregate expression. When a user searches with a formula containing both a conditional clause and a group_aggregate expression, then ThoughtSpot detects the first aggregation type within the conditional clause and uses it in the Table Aggregation summary.
We changed the default behavior for table aggregation summaries when the search contains a formulas that contain both a conditional clause (`if... then... else`) and a group_aggregate expression. When a user searches with a formula containing both a conditional clause and a group_aggregate expression, then ThoughtSpot detects the aggregation type on the first non-constant output clause and uses it in the Headline summary.

For example, in the formula `group_aggregate(sum(if (Color = 'blue') then 0 else group_unique_count(Discount)))`, the headline summary would use `COUNT_DISTINCT`, since the first non-constant output column within the `if... then... else` clause is `group_unique_count` and has an aggregation type of `COUNT_DISTINCT`.
