When I go to latest Ratel (http://localhost:8000/?latest#) → Schema → select a string predicate → check index, Ratel provides me a link to the docs about indexing:
That link points to Query Language - Query language, whereas it should read https://dgraph.io/docs/query-language/schema/#indexing. That section could benefit from an exhaustive list (table) of types and their available indices, which then could link to the respective sub-sections that have details on each data type.
Thanks for pointing that out. I’ve pushed a fix for the link in Ratel.
@MichelDiz what do you think about “a table of available types and indices” ? should we ask the docs team to publish one?
Like this table https://dgraph.io/docs/query-language/schema/#scalar-types?
I think as much information we doc the better.
Maybe the Scalar Types (Maybe not, due space on the columns) could have a new column with the indexes. And link them to each part of it on docs.
Exactly like that table! 
I can confirm the link works.
I’ll accept it, put on the back log. So the docs guys can decide what to do.
