Hi @noxoc
Thanks for the question. Using the repeater field, it will not be possible to query the data as you have asked.
However, it is possible to do so using a plugin called posts 2 posts. This will replace the repeater field on the clients CPT and allow you to connect the client to work.
Then you can use normal WP_Query to get the posts. The posts 2 posts plugin contains new parameters for the WP_Query so you can ask for posts that are connected to works and then also add in the work tax_query.
It will be a bit tricky, but it will be possible.
Thanks
