This pull request focuses on enhancing the retail/interactive-tutorials/search/search-with-ordering.js Node.js sample by incorporating standard region tags. This change is a maintenance fix aimed at improving the sample's integration with documentation systems, allowing for easier and more reliable code snippet extraction.

Highlights

• Documentation Tagging: Added [START] and [END] region tags to the retail/interactive-tutorials/search/search-with-ordering.js file.

Code Review

This pull request adds [START] and [END] region tags to the search-with-ordering.js Node.js sample. This is a useful change for documentation generation purposes.

While reviewing the code within the newly added region tags, I identified a potential improvement for robustness. In search-with-ordering.js, the main function calls callSearch() without using await. Although the script may function correctly in this isolated case because the Node.js process waits for the event loop to be empty, it is a best practice to await asynchronous function calls. This ensures a predictable execution order and more straightforward error handling. I recommend changing callSearch(); to await callSearch(); on line 76.

Since this feedback applies to code outside of the changed lines in this PR, I'm including it here as a general comment for your consideration.
