Issue

The Elasticsearch fields limit is wrong resulting in the following error when executing [catalogsearch_fulltext] indexer:

Limit of total fields [xxx] in index [xxxxxx] has been exceeded

This issue occurs when you have a large number of product attributes. The issue is triggered by the way Elasticsearch calculates the field count. Sometimes when there are attributes that have fields assigned to them these fields will index as separate indexers. This results in the limit having been exceeded warning.

Steps to reproduce:

Prerequisites

  • Installed module-elasticsearch 100.3.5.
  • Elasticsearch 7 installed.
  • Set up Elasticsearch as a search backend.
  1. Create more than 1000 attributes for products.
  2. Create products for each family.
  3. Run indexer.

Expected result:

All products are available in the Elasticsearch index.

Actual result:

  1. Elasticsearch error:

    code language-none 
     {"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Limit
 of total fields [3000] in index [magento2_product_2_v11] has been exceeded"}],"type":"illegal_argument_exception","reason":"Limit
 of total fields [3000] in index [magento2_product_2_v11] has been exceeded"},"status":400}

  2. New product was not indexed.
