I see that all documents I can find inside of filings search response are represented by arrays with one element inside. I would like to map it to a more straightforward structure and map the array with the object to a plain object. But I am not sure if my assumption is correct and all arrays consist only of one object. So does this array always consist of one element? Are there situations when there are 2 or more elements? If there are such cases, what do these array elements represent?
Thank you in advance
