# [Search Configuration interface](../../../lib/content-services/src/lib/common/interfaces/search-configuration.interface.ts "Defined in search-configuration.interface.ts")
|
|
|
|
Provides fine control of parameters to a search.
|
|
|
|
## Methods
|
|
|
|
`generateQueryBody(searchTerm: string, maxResults: string, skipCount: string): QueryBody`<br/>
|
|
Generates a QueryBody object with custom search parameters.
|
|
|
|
## Details
|
|
|
|
The interface defines a service that generates a custom
|
|
[QueryBody](https://github.com/Alfresco/alfresco-js-api/blob/1.6.0/src/alfresco-search-rest-api/docs/QueryBody.md)
|
|
object. This object can then be supplied to a search operation to refine the search parameters.
|
|
|
|
A standard implementation, the
|
|
[Search Configuration service](../services/search-configuration.service.md) is provided in the ADF Core library
|
|
source. This works fine in most cases but if you need to, you can implement your own service, as
|
|
described below.
|
|
|
|
### How to use the interface
|
|
|
|
1. Implement the service class
|
|
|
|
Create your own service class to implement the [`SearchConfigurationInterface`](../../core/interfaces/search-configuration.interface.md). This defines the
|
|
the `generateQueryBody` method that returns the QueryBody object. See the
|
|
[QueryBody](https://github.com/Alfresco/alfresco-js-api/blob/1.6.0/src/alfresco-search-rest-api/docs/QueryBody.md)
|
|
page in the Alfresco JS API for further details about the options this object provides.
|
|
|
|
An example implementation is given below:
|
|
|
|
```ts
|
|
import { QueryBody } from '@alfresco/js-api';
|
|
import { SearchConfigurationInterface } from '@alfresco/adf-core';
|
|
|
|
export class TestSearchConfigurationService implements SearchConfigurationInterface {
|
|
|
|
constructor() {
|
|
}
|
|
|
|
public generateQueryBody(searchTerm: string, maxResults: string, skipCount: string): QueryBody {
|
|
const defaultQueryBody: QueryBody = {
|
|
query: {
|
|
query: searchTerm ? `${searchTerm}* OR name:${searchTerm}*` : searchTerm
|
|
},
|
|
include: ['path', 'allowableOperations'],
|
|
paging: {
|
|
maxItems: maxResults,
|
|
skipCount: skipCount
|
|
},
|
|
filterQueries: [
|
|
{ query: "TYPE:'cm:folder'" },
|
|
{ query: 'NOT cm:creator:System' }]
|
|
};
|
|
|
|
return defaultQueryBody;
|
|
}
|
|
}
|
|
```
|
|
|
|
2. Provide your service class to the module
|
|
|
|
Once you have created your service class, you must inform the component to use it instead
|
|
of the default one. This is easily done using the component providers:
|
|
|
|
```ts
|
|
import { SearchService, SearchConfigurationService } from '@alfresco/adf-core';
|
|
import { TestSearchConfigurationService } from './search-config-test.service';
|
|
|
|
@Component({
|
|
selector: 'app-search-extended-component',
|
|
templateUrl: './search-extended.component.html',
|
|
styleUrls: ['./search-extended.component.scss'],
|
|
encapsulation: ViewEncapsulation.None,
|
|
providers: [
|
|
{ provide: SearchConfigurationService, useClass: TestSearchConfigurationService },
|
|
SearchService
|
|
]
|
|
})
|
|
```
|
|
|
|
You also need to add the [`SearchService`](../../core/services/search.service.md) as a provider to avoid overriding the module instance. This component will have his own instance of the [`SearchService`](../../core/services/search.service.md) that will use the class you have provided
|
|
as its configuration.
