Content (please ensure you mask any confidential information):

We are developing a page where one of feature needed is the ability to search for items, similar to the SSP Item Search option. We found the following REST API Path: from Oracle docs.

Path: /fscmRestApi/resources/11.13.18.05/shoppingSearches/{SearchPhraseId}

We are trying to use this API but not able to get it work. We have following questions, hoping to get some experts advice and inputs.

1. Is this the right API to serve the purpose?
2. What is the parameter 'SearchPhraseId' to pass?
