It is because `count` counts documents, not fields. ---

Thanks @richcollier. How to count the numbers in ml job. Ex: I got 404 response code 100 times in past two days. How do i forecast in next 5 days how many times the 404 response code will occur. Without using the count, how do I achieve the same? could you please help me ---

1. Create a search that returns 404 response codes: (i.e. - `status:404`) ![image](https://us1.discourse-cdn.com/elastic/original/3X/0/f/0f5d2206b689fb4c4273735e3b7b1d7c03700e4d.png) 1. save this search ![image](https://us1.discourse-cdn.com/elastic/original/3X/1/c/1c9a69c8b0a198cd00a4a880ed96e235026a6d5b.png) 1. Create job from saved search ![image](https://us1.discourse-cdn.com/elastic/original/3X/3/0/30b6779cf65f2d9c69d5d8511326378368885b26.png) 1. Select `count` aggregation and appropriate bucket\_span ![image](https://us1.discourse-cdn.com/elastic/original/3X/7/5/7556b5ac1fd1f43e2bdc11a8f0df6c050a320fd4.png) 1. Run job as much historical data as possible, get results ![image](https://us1.discourse-cdn.com/elastic/original/3X/e/f/ef8ff37c47a75212839fec641254884cd1684eab.png) 1.
