Could you do your best dunk on ES for me please? Not as in factually great, just whatever. I (ab)use quite a bit in my work, and can't say I have particularly strong opinions/feelings around it either way - I could use some help to change that xD
My most recent complaint is about index mappings. I have 2 types in 2 different indexes that each have a field with the same name. One index has a hand written mapping. The other index is currently under active development and doesn't have a mapping for it yet so it's built automatically. When I insert into the index WITHOUT a mapping, the index WITH a mapping changes the field into a keyword and no further queries against the index WITH a mapping work. This also happens if I insert into the index WITHOUT a mapping before the other index is created. Why does the index WITH a mapping change?!? WE WROTE THE MAPPING FOR A REASON BUT ITS IGNORED!?!
