At this time, the Live Search search/category API has the following supported limits and static boundaries:
Indexes up to 300 product attributes per store view
Indexes only products from the Adobe Commerce database
Does not index CMS pages
Live Search can manage up to 200 synonyms per Data Space ID.
Live Search does not have access to the full taxonomy of the category tree, which makes some layered navigation search scenarios beyond its reach.
Live Search uses a unique GraphQL endpoint for queries to support features such as intelligent faceting and search-as-you-type. Although similar to the Magento GraphQL API, there are a few differences and some fields may not be fully compatible at this time.
PWA beta release
The current beta PWA implementation of Live Search requires more processing time to return search results than Live Search with the native Commerce storefront.
The beta release of PWA for Live Search does not support event handling.
The following product attributes are not supported by GraphQL when used in relation to the beta release of PWA: description, name, short_description
Not supported at this time
The Advanced Search module is disabled when Live Search is installed, and the Advanced Search link in the storefront footer is removed.
