search(request, options)

search(request?: protos.google.cloud.retail.v2alpha.ISearchRequest, options?: CallOptions): Promise<[
        protos.google.cloud.retail.v2alpha.SearchResponse.ISearchResult[],
        protos.google.cloud.retail.v2alpha.ISearchRequest | null,
        protos.google.cloud.retail.v2alpha.ISearchResponse
    ]>;

Performs a search.

This feature is only available for users who have Retail Search enabled. Please enable Retail Search on Cloud Console before using this feature.

Parameters
NameDescription
request protos.google.cloud.retail.v2alpha.ISearchRequest

The request object that will be sent.

options CallOptions

Call options. See CallOptions for more details.

Returns
TypeDescription
Promise<[ protos.google.cloud.retail.v2alpha.SearchResponse.ISearchResult[], protos.google.cloud.retail.v2alpha.ISearchRequest | null, protos.google.cloud.retail.v2alpha.ISearchResponse ]>

{Promise} - The promise which resolves to an array. The first element of the array is Array of [SearchResult]. The client library will perform auto-pagination by default: it will call the API as many times as needed and will merge results from all the pages into this array. Note that it can affect your quota. We recommend using searchAsync() method described below for async iteration which you can stop as needed. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#auto-pagination) for more details and examples.

search(request, options, callback)

search(request: protos.google.cloud.retail.v2alpha.ISearchRequest, options: CallOptions, callback: PaginationCallback<protos.google.cloud.retail.v2alpha.ISearchRequest, protos.google.cloud.retail.v2alpha.ISearchResponse | null | undefined, protos.google.cloud.retail.v2alpha.SearchResponse.ISearchResult>): void;

callback PaginationCallback<protos.google.cloud.retail.v2alpha.ISearchRequest, protos.google.cloud.retail.v2alpha.ISearchResponse | null | undefined, protos.google.cloud.retail.v2alpha.SearchResponse.ISearchResult>
Returns
TypeDescription
void

search(request, callback)

search(request: protos.google.cloud.retail.v2alpha.ISearchRequest, callback: PaginationCallback<protos.google.cloud.retail.v2alpha.ISearchRequest, protos.google.cloud.retail.v2alpha.ISearchResponse | null | undefined, protos.google.cloud.retail.v2alpha.SearchResponse.ISearchResult>): void;
Parameters
NameDescription
request protos.google.cloud.retail.v2alpha.ISearchRequest
callback PaginationCallback<protos.google.cloud.retail.v2alpha.ISearchRequest, protos.google.cloud.retail.v2alpha.ISearchResponse | null | undefined, protos.google.cloud.retail.v2alpha.SearchResponse.ISearchResult>
Returns
TypeDescription
void

searchAsync(request, options)

searchAsync(request?: protos.google.cloud.retail.v2alpha.ISearchRequest, options?: CallOptions): AsyncIterable<protos.google.cloud.retail.v2alpha.SearchResponse.ISearchResult>;

Equivalent to search, but returns an iterable object.

for-await-of syntax is used with the iterable to get response elements on-demand.

Parameters
NameDescription
request protos.google.cloud.retail.v2alpha.ISearchRequest

The request object that will be sent.

options CallOptions

Call options. See CallOptions for more details.

Returns
TypeDescription
AsyncIterable<protos.google.cloud.retail.v2alpha.SearchResponse.ISearchResult>

{Object} An iterable Object that allows [async iteration](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols). When you iterate the returned iterable, each element will be an object representing [SearchResult]. The API will be called under the hood as needed, once per the page, so you can stop the iteration when you don't need more results. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#auto-pagination) for more details and examples.

{Stream} An object stream which emits an object representing [SearchResult] on 'data' event. The client library will perform auto-pagination by default: it will call the API as many times as needed. Note that it can affect your quota. We recommend using searchAsync() method described below for async iteration which you can stop as needed. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#auto-pagination) for more details and examples.
