Filtered aggregation functions
You can create a filtered aggregation in the search bar.
Filters are useful for queries where the results should reflect a new, filtered value. On this page you learn about comparative versus derivative filters, and the functions, and the keywords that you can use with them.
Comparative filters compare two segments of some whole against each in the Search bar. For example, a company that has locations across the United States, may want to compare total revenue in the West to the East segment. In a comparative filter, one of the segments you are comparing is filtered.
An example of a comparative filter is comparing west revenue with total revenue.
In these cases, one measure is a filtered measure, for example,
revenue region = west is a filtered measure.
Derivative filters add a column to your results which is derived from other columns in the same results. For example, you search for revenue and cost and want to calculate profit in your result.
Some examples of comparative and derivative filters in the real world are:
revenue of this_soap versus all_soaps (Comparative filter)
tax as a percentage of revenue (derivative)
count revenue as a percentage of state revenue (comparative with a derivative)
If you plan to create these types of filters, you need to understand how to create filter functions.
Filter functions take two arguments, the column ( measure or attribute) to aggregate and the filter condition:
FUNCTION_NAME(condition, <column name>)
ThoughtSpot functional library will include the following functions:
Consideer the following examples of these functions:
Aggregates only the revenue for the values that correspond to the west region.
count_if(region ='west', region)
Aggregates only the region for the values that correspond to the west region.
count_if(revenue > 100, red)
Counts the number of times red appears when revenue is greater than
100(row-level revenue data, not aggregated).
A condition can have multiple filters, like the two conditions for
region in the example
sales region = west OR region = east.
You can also just type a value as a filter; here,
east is the filter in the expression
If there are no rows matching the filter criteria, the condition returns a
0 (zero). When you use a filter rather than a filter function, ThoughtSpot does not include any zero values in your chart or table. Using a filter function like
count_if is the best way to include zero values in your chart or table.
A 0 can result in situations where there are logic errors in the formula, so be sure to verify your work.
After you have aggregated with a filter, you can do further comparisons with the

It compares a measure across different sets of filters and or groupings.
The basic format of a comparison search is:
<common search tokens> (A vs
B) <common search tokens>
revenue region last 10 years vs all
Try this syntax on using the The superstore example data.
vs example compares two segments with a single search token:
The system automatically applies the
sales token to both sides and groups each segment.
You can use the
all keyword to break out the segments and avoid grouping.
You can also provide multiple
Of course, you can compare across different columns as well:
