NodeJS + MongoDB Search Expert (filters + autocomplete search)

For a web application built in NodeJS I am looking for someone to help me with the Search options. The web application is deployed on Heroku and uses MongoDB, Pug and NodeJS. My database consists of humans, dogs, cats and people should be able to search in this database. (See Image for example). The objects in the database have two names (birthname and sportname), so if people start typing in the field "Name" it should search the database in the fields birthname and sportname. Ideally it should have an autocomplete function (like Google) after two characters. The fields "Father" and "Mother" work similar. For Category it should like in the categoryfield of the database (this is an array), this logic is similar for Type and Guarantuee. For Price, Height and Age he needs to look in a range of the database. Currently this range is made with NoUiSlider but this can be done with something else if necessary. I can write down the exact details if necessary. Ideally it should be finished by the end of October, but it is not really urgent :) If you could help me out with other small things that would be great!
