I have been searching around for answers for a while and just counldn't seem to find one.

Here is the question:

1. when use multipleSearch = true, is it possible to combine search fields in the main grid and the subgrid? Or,

2. when use filterModel (manually add fields from both main grid and subgrid), is it possible to add operators ( I mean search sopt, 'eq', 'le',…) like when multipleSearch is enabled?

It seems like there is no good way mix the features of these 2, or I just haven't find the right place.

Really appreciate your feedback. Thanks!
