Is there a ready/almost ready solution for image search (content-based image retrieval)?

Question

PHP

Good afternoon.
Interested in the topic of image search, can someone advise a solution.
The server has an array of images, 30k - 50k pictures.
A photo/drawing is sent to the server via api.
You need to figure out how to quickly compare and find the most suitable option from the images stored on the server.
From what I dug up:
Soil + Lire
Elasticsearch + Image Plugin (one of the forks)
In both cases, there is enough trouble with installation and configuration and integration into a test project.
Ideally, you need some kind of library that is easy to install on the server and that can scan local images, create an index, and search-compare the transmitted image on it.
Any ideas?

google phash. There is an extension for php, I wrote in pure php. There is an implementation in java. You calculate the hashes, save them in the database, then calculate the Hamming distance from them and take where it is less, this is the most suitable picture.
