Azure cognitive search alternative

Question

I am looking for an azure cognitive search alternative on an other cloud service. Basically I like the idea to upload, search, upgrade and delete objects in cognitive search via a REST API with less programming effort. The alternative should be able to store up to 50.000 objects which cause ~200mb memory load and provides a good search engine. Or do you folks know a way to search text in a postgres DB, which provides suggestions and spelling correction?

The actual problem is that azure cognitive search becomes very expensive as soon one needs the first plan (~80$ a month).

You can basically build similar service using a combination of OCR , NLP and Search (Elastic search) so on AWS I would try Textract , Sagemaker , Amazon Comprehend , Elasticsearch you can find an example here

I used elasticsearch for autocomplete and auto suggestion and spell check, it is very powerful depending on the type of suggester you want :
