Combining and Sorting Search Results from Two Collections

hi, i've got a question about "_text_match" and trying to combine search results from two collections that are in a federated search.

i'm doing a federated search of two different collections and i get the data back listed as results from collection1 and then results from collection2. i'm trying to avoid combining them into one collection at the moment, so i thought maybe if i put the results together, i could get the value of _text_match from all the results and programmatically sort the results of the federated search that way

Yes text_match is exposed as a field in the results.

Thanks!
