## isNewQuery() function

Compares two queries to know if the new one is a refined query from the previous one or a new one.

A refined query is a query which has the previous query or part of it. Example: - previousQuery = 'lego star'. - newQuery = 'lego star wars'.

Example: - previousQuery = 'lego star wars'. - newQuery = 'lego star'.

A new query is a query which has not the previous query. Example: - previousQuery = 'lego star'. - newQuery = 'lego wars'.

In this case, it is changing the word set, because a word is changed by another one, so this is changing the search intention.

**Signature:**

```typescript
export declare function isNewQuery(newQuery: string, previousQuery: string): boolean;
```

## Parameters

|  Parameter | Type | Description |
|  --- | --- | --- |
|  newQuery | string | The new query. |
|  previousQuery | string | The previous query. |

**Returns:**

boolean

A boolean which flags if the query is refined or not.
