# Database

> Blocknative local sync: searchable entities, `.search()` filters, and operators.

The Blocknative plugin syncs data locally. Use `corsair.blocknative.db.<entity>.search({ data, limit?, offset? })` with the filters listed per entity.

<Info>
  **New to Corsair?** See [database operations](/concepts/database), [data synchronization](/concepts/integrations), and [multi-tenancy](/concepts/multi-tenancy).

## Base Fee Estimates

Path: `blocknative.db.baseFeeEstimates.search`

```ts theme={null}
const rows = await corsair.blocknative.db.baseFeeEstimates.search({
    data: { /* filters below */ },
    limit: 100,
    offset: 0,
});
```

### Searchable filters

| Field                | Type     | Operators                                  |
| -------------------- | -------- | ------------------------------------------ |
| `entity_id`          | `string` | equals, contains, startsWith, endsWith, in |
| `system`             | `string` | equals, contains, startsWith, endsWith, in |
| `network`            | `string` | equals, contains, startsWith, endsWith, in |
| `unit`               | `string` | equals, contains, startsWith, endsWith, in |
| `currentBlockNumber` | `number` | equals, gt, gte, lt, lte, in               |
| `msSinceLastBlock`   | `number` | equals, gt, gte, lt, lte, in               |
| `baseFeePerGas`      | `number` | equals, gt, gte, lt, lte, in               |
| `blobBaseFeePerGas`  | `number` | equals, gt, gte, lt, lte, in               |

*Every `.search()` also accepts `limit` and `offset` for pagination. `.list()` is available on the same path without the `.search` suffix in code — see [database operations](/concepts/database).*
