To interact with Rest Webservice, I make use of the various conditions available for input parameters to perform a search and it displays the list of records that matches the search condition.
You can pass multiple values for the specified field in a couple of ways. Either you can use the inbuilt search available on the web page or you can add the filter condition in the URL.
1.**Web page search **
In order to pass the multiple values for the specified field, I would perform the below steps
* On the web page, click on the ‘search view’ button and select the Input parameters filed. For example, ‘employee_id’.
* Select the “iscontained” condition from the drop-down.
* Enter the values as ‘02019590, 02019592, 02019593’ and click on the search.
* Now I was able to view records based on the condition.
2.**Adding filter condition**
You can also use the $filter parameter in the URL.The $filter parameter which filters the rows of a view similar to the where conditions.For example,
> http://<Host>:<port>/server/<database>/<web-services>/views/<web-services>?$filter=<filed_name> in (<value1>,<value2>..<valuen>)
Also, for dynamically changing the values in the filter parameter, I would make use of [Interpolation variables](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/creating_data_sources_and_base_views/path_types_in_virtual_dataport/path_types_in_virtual_dataport#paths-and-other-values-with-interpolation-variables) (like, ?$filter=@variable) and provide the value for this variable during each execution dynamically.
For more information, you can refer to the [Input Parameters of the RESTful Web Service
](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/restful_architecture/restful_web_service/input_parameters_of_the_restful_web_service#parameters-supported-by-the-denodo-restful-web-service-and-published-rest-web-services) section of the Virtual DataPort Administration Guide.
Hope this helps.
