An easy refactor for your function is to use a "Builder" for your params, i.e.:

options = NodeBuilder .author({ min: 2 }) .flag({ .. }) .pagitation({ .. })

function a_nodes_list_trees(options) { ... }

Because in the end, if your function is fast and working correctly, it's fine even though it's a little bit messy. The problem is more all the code calling this function and having to pass dozens of params in the right order, and then it's a pain to start adding/changing parameters. Also, when calling this function, you probably need a bunch of temporary variables to "build" all the params; all those temporary variables could instead live inside that builder object.
