Woocommerce Rest API Bug

We are using your PRO version 2.14, I want to report a Bug related to Table re-indexing.

We are Creating/Updating products using Woocommerce Rest API V2.
I know for the first time we need to Re-index Table once & later on it will auto re-index as mentioned in the plugin settings.
When we create any new product using Rest API it appears in search result. When we update any product title using Rest API product still appears in search results.
But when we change the Product Category or add Product Tag & Update the product using Rest API and when we search product with this New Product Category or New Product Tag it doesn’t appear in Search Results until I manually go and click on Reindex Table button from plugin setting.
Please help !
