It's still pre-1.0 so I could break them, but I've also built my own code against this in the past so it's likely other people have too.
If I don't break them, I will instead need to come up with a naming convention for those keys - something like `""tags__array""` for example. As well as a way to ensure that a column called `tags__array` doesn't end up conflicting with the `tags__array` key!","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",520740741,If you apply ?_facet_array=tags then &_facet=tags does nothing,

It looks like this:
```
""facet_results"": {
""tags"": {
""name"": ""tags"",

""hideable"": false,

""truncated"": false
},
""created"": {
""name"": ""created"",
""type"": ""date"",

The problem then is that the `tags` key is over-ridden by the second facet with a different type against the same column name!
