# Fase 4 — Search contextual + Advanced Search

**Programa:** Work Orders Board  
**Objetivo:** Hardening da busca contextual no board semanal, endpoint de advanced search cross-week (Tier S), índices de suporte e harness de load test.

**Depende de:** [Fase 0](../phase-0/README.md), [Fase 1](../phase-1/README.md), [Fase 2](../phase-2/README.md), [Fase 3](../phase-3/README.md)

**Tier vigente (dev):** **S (provisório)** — ver [search-tier-decision.md](./search-tier-decision.md)

## Endpoints

### `GET /api/workorders/board?search=` (hardening)

Busca contextual na janela semanal. Campos cobertos:

| Campo | Origem |
|-------|--------|
| Site | `SiteCode` |
| WO# | `InternalWONumber`, `WorkerOrderNumber` |
| Location | `Locations.Name` |
| Dispatcher | `AssignToUser` nome |
| PM | `Trade`, `Problem` |
| Vendor | `PrimaryDispatch.Vendor.CompanyName` |
| Tech | `PrimaryDispatch.Vendor.ContactName` |
| Status legado | `Status` |
| Lifecycle | label enum (`Scheduled`, `In Progress`, etc.) |

**Regras:**

- `search` com trim; ignorado se vazio ou < 2 caracteres
- `counts.total` — agendadas na semana **sem** search
- `counts.returned` — agendadas **com** search

### `GET /api/workorders/board/search`

Advanced search cross-week paginado.

**Autenticação:** Bearer JWT

**Query params:**

| Param | Tipo | Descrição |
|-------|------|-----------|
| `search` | string | Texto livre (mesmos campos do contextual) |
| `datePreset` | enum | `thisWeek`, `lastWeek`, `thisMonth`, `last3Months`, `nextWeek`, `nextMonth`, `custom` |
| `dateFrom` / `dateTo` | date | Obrigatórios se `datePreset=custom` |
| `sites` | string[] | `SiteCode` |
| `types` | WorkOrderType[] | Tipo WO |
| `dispatchers` | string[] | GUIDs + `__unassigned__` |
| `statuses` | LifecycleStatus[] | Status operacional |
| `pmTypes` | string[] | Match em `Trade`/`Problem` (contains, case-insensitive) |
| `vendorIds` | int[] | Via `PrimaryDispatch.VendorId` |
| `docStatuses` | DocStatus[] | Enum `DocStatus` |
| `myWorkOrders` | bool | Filtro usuário logado |
| `page` | int | Default 1 |
| `pageSize` | int | Default 50; max 100 (Tier S/M) |
| `sortBy` | string | `scheduledDate` (default), `woNumber`, `dueDate` |
| `sortDir` | string | `asc` / `desc` |

**Response:** `PagedResult<WorkOrderBoardRowDto>`

```json
{
  "items": [ /* WorkOrderBoardRowDto */ ],
  "totalCount": 120,
  "page": 1,
  "pageSize": 50,
  "totalPages": 3,
  "hasNext": true,
  "hasPrevious": false
}
```

**Exemplo:**

```bash
curl -H "Authorization: Bearer <token>" \
  "https://localhost:5001/api/workorders/board/search?datePreset=thisMonth&sites=BK5&search=HVAC&page=1"
```

## Matriz preset → intervalo de datas

Base: **segunda-feira ISO** (`WorkOrderSearchDateRangeResolver`).

| Preset | Intervalo |
|--------|-----------|
| `thisWeek` | Seg–Dom da semana ISO corrente |
| `lastWeek` | Seg–Dom da semana ISO anterior |
| `nextWeek` | Seg–Dom da próxima semana ISO |
| `thisMonth` | 1º–último dia do mês corrente |
| `nextMonth` | 1º–último dia do mês seguinte |
| `last3Months` | Hoje − 3 meses → hoje |
| `custom` | `dateFrom` / `dateTo` (400 se ausentes) |

**Filtro de data:** `ScheduledDate` no intervalo **OU** `ScheduleWeekOnly && TargetWeek` intersectando o intervalo. Exclui templates e `IsDeleted`.
