Answer 1

Most likely reason is that you are lacking ElasticSearch installed, which is a Magento 2 requirement since 2.3. If this proves to be the case, all category pages will also return the same error.

Check correct version at https://devdocs.magento.com/guides/v2.4/install-gde/system-requirements.html

See var/log/exception.log - if you see Elasticsearch related errors, that's the case.

Once installed, check connection in Stores > Configuration > Catalog > Catalog > Catalog Search > [Test Connection] button.

Once connection is successful, issue bin/magento indexer:reindex catalogsearch_fulltext.

Beware that Full page cache seems to cache this error, so once fixed, please do bin/magento cache:clean full_page to verify.

Answer 2

You can go to CLI and execute command to check whether its installed or not

service elasticsearch status.

Answer 3

You might want to give the Elasticsuite module a try. For my taste, it works better than the default Magento Elasticsearch module but your mileage may vary.

Answer 4

Can you post the attributes that you have set to searchable. What's the data type associated with the attributes.

Also you need to make sure that the elastic search needs to be reindexed. We faced the same problem.

The finding was that one of the attribute was from an external module and was set to search as true while that attribute was not getting indexed.

SO if any external modules adding attributes as searchable first those from searchable, Reindex attributes then reindex search and check.
