Aggregate API

Our Aggregation API provides high-level calculations on top of our Search API.

Using Aggregations, you can power dashboard and run high-level analysis on the results of your searches. Aggregations use the same Lucene-based logic as the search API, and results are returned as ordinary JSON documents.

🚧

No query wrapping required.

Unlike a request to the Search API, request to the Aggregation endpoints do not require the query to be wrapped in a query object.

Term Aggregate

Endpoint:https://api.platform.datastreamer.io/api/aggregate/term

Here are a couple of important points that need to be considered before consuming the Term Aggregate endpoint.

• You can only perform an aggregation on the most recent 30 days, and timeframes within 30 days can be narrowed using date range filtering.
• Query uses all the possible Terms, Phases, and Modifiers as briefed under the Query section.
• Field can be set to any of the following.

Date Histogram Aggregate

Endpoint:https://api.platform.datastreamer.io/api/aggregate/date_histogram

What is a Histogram?

A histogram is an approximate representation of the distribution of numerical data.

Here are a couple of important points that need to be considered before consuming the Date Histogram endpoint.

• You can only perform an aggregation on the most recent 30 days, and timeframes within 30 days can be narrowed using date range filtering.
• The query within a Date Histogram can use all the possible Terms, Phases and Modifiers as briefed under Query, Metadata fields, and Enrichment sections.
• Data automatically adapts in resolution to the timeframes being requested. Therefore, a request for 10-minute segment will provide closer to per minute, while a week would provide daily. Searching 30 days will segment into 3 day buckets.

This is an approximation as, the API automatically calculates a date interval that will not exceed 10 buckets.
