## What it is
Sieve is a .NET Core library that adds sorting, filtering, and pagination to ASP.NET Core APIs, typically applied to Entity Framework queries in GET endpoints. It uses attributes or a fluent API to declare which model properties are sortable and filterable, and processes client-supplied query parameters via a SieveModel.

## Use cases
- add sorting, filtering, and pagination to ASP.NET Core GET endpoints
- let clients sort and filter API results via query parameters
- paginate large Entity Framework query results
- declare filterable and sortable model properties with attributes or a fluent API
- add custom sort and filter methods to API queries

## When to choose
- you're building an ASP.NET Core REST API backed by EF Core and need consistent list-endpoint querying
- you want a lightweight, declarative alternative to hand-writing sort/filter/pagination logic
- you need extensible custom filter/sort behavior per entity

## When to avoid
- you're not on .NET / ASP.NET Core
- you need full-text or fuzzy search rather than simple field filtering
- you want GraphQL-style flexible querying or OData
- the project appears to be in maintenance with limited recent feature development
