Elasticsearch + "we can't find products matching the selection"

[caos989]

Hi,

I installed a testshop with Magento 2 and made a clone of this testshop.

Everytime when I switch on Elasticsearch I get this error: "we can't find products matching the selection" when I click on a Category.

I saw that there is a prefix and it was the same at the testshop + clone. So I changed the prefix but I'm still getting this error. Can somebody help?

Magento 2.3.7

Elasticsearch: 7

Hello @caos989 

Please check the indexer of the elastic search so you need to apply the reindex of your elastic search.

May your issue get solved.

I'm new with elasticsearch. Can you tell me how to reindex?

Hello @caos989 

If the elastic search is configured with Magento then the re-index command is the same as the Magento command.

I installed elasticsearch first than I installed Magento and connected it in the configuration.

When I reindex Magento with php bin/magento indexer:reindex it stays like it is.

Is there some other option to reindex elasticsearch?

Hello @caos989 

Elasticsearch is not connected with magento. You can check the connection in the store configuration.

For me it seems like the configuration is correct. I can make a connection test and I get a successfull.

I found the solution.

in my debug.log there was: [2022-05-12 11:20:18] main.CRITICAL: {"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Text fields are not optimised for operations that require per-document field data like aggregations and sorting, so these operations are disabled by default. Please use a keyword field instead. Alternatively, set fielddata=true on [weight] 

So i checked the Attribute weight and it was set yes

I changed it to no. Reindex and now I can see the products.
