I would like to amend the code around here so we can retrieve the full set of symbols that would be components of an index. For instance the ^FTAS has 662 components as of today but you can only get 51 back via YQL, if someone could give me some pointers on how to fix and test this I will make the changes and commit it back into the main repo.
I had the same problem and created my own table definition for this.
I would be happy to contribute it to the main repo.
Does this still work?
