用法

 public class ApplicationDbContext : DbContext
{
    // ...

    protected override void OnModelCreating ( ModelBuilder modelBuilder )
    {
        base . OnModelCreating ( modelBuilder ) ;

        // ...

        modelBuilder . Entity < Post > ( )
            . HasIndex ( g => g . Content )
            . HasMethod ( "pgroonga" )
            . HasOperators ( "pgroonga_varchar_full_text_search_ops_v2" ) ;

    }
}

public class Startup
{
    // ...

    public void ConfigureServices ( IServiceCollection services )
    {
        services . AddDbContextPool < ApplicationDbContext > ( options =>
            options . UseNpgsql ( Configuration . GetConnectionString ( "DefaultConnection" ) ,
            builder => builder . UsePGroonga ( ) ) ) ;

        // ...
    }
}

var posts = await _dbContext . Posts . Where ( g => g . Content . SimilarSearch ( q ) )
    . OrderByDescending ( g => EF . Functions . PgroongaScore ( ) )
    . ToArrayAsync ( ) ;
