But after glancing at some of the former code for this feature I'm curious how this was implemented in the past. Its just that I feel the current implementation is way to directed towards being easy to learn for newcomers by doing many things automatically behind the curtains instead of by having a well written documentation and demo projects on how to implement it into an already existing concept // infrastructure. privacy statement. So how can we confirm its working? Are you sure you want to hide this comment? Full text search is what Google and other search engines do for web pages.

Using regex-filters would give the possibility to create a case-insensitive "search". After working with Prisma professionally the last 3 years I followed it evolving to a somewhat mature product and would like to see this lib reach the same granularity and function set while being driven by the apex graphDB. Aug 1, 2018 17 In this tutorial, we'll learn how to implement GraphQL search in a React. All rights reserved. We're a place where coders share, stay up-to-date and grow their careers. Tech Enthusiast. I'm using this lib for 3 Proof of concept projects at the moment and I still love it, but I basically have to override everything to suit an actual business logic middleware and only use the generated OGM client (wich is awesome btw). Enable full-text search in the queries Use Atlast's RBAC API Endpoint Example (.NET) Postgres Database (only one database) Use full-text search in Postgres Hand Crafted GraphQL on top of Postgres with full-text search querying Use Postgres's RBAC What tech stack / architecture would you use and how would you achieve this? A lower maximum value will return fewer documents. What tech stack / architecture would you use and how would you achieve this?

Object types, scalars, and enums are the only kinds of types you can define in GraphQL. fulltextsearch is not case-sensitive. Most upvoted and relevant comments will be first, Instant Realtime GraphQL APIs on your data, Save Time and Stop Writing GraphQL Resolvers, GraphQL Security in Production with Automated Allow Lists, The rise of GraphQL APIs on data warehouses. A better approach is to design an Input Type containing all the possible filtering (or sorting) options necessary, and use that as a single parameter, encapsulating all of the arguments for the field. The query should return all products in the database that match, but it should not return restricted products for premium members because they do not have access.
