search on child post value is possible?

Hi

I have a parent-child relationship post types in child post type
it has title field(text box) , language field(drop down) , and some text field(text box) in grid view with multiple rows
lets say language has different values for every text box.

so my question is here can i search records on listing page on the basis of language value that is present in child post custom field.
is it possible in type? like category and title we always use to search the exist record on listing page?

Thanks
