### Optimizing Search Schema Design for Entity Endpoints

type SearchBody = {
  match: {
    _id?: ObjectId,
    fieldA?: string,
    fieldB?: string,
    // etc
  },
  matchType: "AND" | "OR",
  pagination: {
    page: number,
    limit: number
  },
  sort: {
    field: string,
    direction: "ASC" | "DESC"
  }
}

export class SearchSchema extends Schema.Class<SearchSchema >("SearchSchema")({
  sort: Schema.optionalWith(SortRequestSchema, {
    default: () => new SortRequestSchema({ field: "_id", direction: -1 }),
  }),
  pagination: Schema.optionalWith(PaginationSchema, {
    default: () => new PaginationSchema({ limit: 25, page: 1 }),
  }),
}) {}

export class SearchTodoSchema extends SearchSchema .extend<SearchTodoSchema >(
  "SearchTodoSchema",
)({
  match: S.Struct({
    _id: S.optional(ObjectIdSchema),
    description: S.optional(S.String),
    userId: S.optional(UserIdSchema),
    done: S.optional(S.Boolean),
  }),
}) {}
