Magento 2.4.2 Elasticsearch Error: main.CRITICAL: {“error”:{“root_cause”:[{“type”:“query_shard_exception”,“reason”:"failed to create query

Question

Elasticsearch not working with main.CRITICAL: {"error":{"root_cause":[{"type":"query_shard_exception","reason":"failed to create query. I have tested the connection in the backend and it's showing successfull. But on the front-end in the catalog search, no result is showing. I have checked in exception.log and the following error is showing:

main.CRITICAL: {"error":{"root_cause":[{"type":"query_shard_exception","reason":"failed to create query:
{ "bool" : { "must" : [ { "terms" : { "visibility" : [ "3", "4" ], "boost" : 1.0 } } ], "should" : [ { "match" : { "_search" : { "query" : "sams sams", "operator" : "OR", "prefix_length" : 0, "max_expansions" : 50, "fuzzy_transpositions" : true, "lenient" : false, "zero_terms_query" : "NONE", "auto_generate_synonyms_phrase_query" : true, "boost" : 2.0 } } }, { "match" : { "name" : { "query" : "sams sams", "operator" : "OR", "prefix_length" : 0, "max_expansions" : 50, "fuzzy_transpositions" : true, "lenient" : false, "zero_terms_query" : "NONE", "auto_generate_synonyms_phrase_query" : true, "boost" : 2.0 } } }, .

}\ }","index_uuid":"fMJ-vmT5Qu2_9PX3yJvMsw","index":"digi_live_product_1_v6","caused_by":{"type":"number_format_exception","reason":"For input string: \"sams sams\""}}}]},"status":400} at
vendor/elasticsearch/elasticsearch/src/Elasticsearch/Connections/Connection.php:632)"} []

I have tried every possible way like restart elastic search and reindex Magento but not working.
Magento version: 2.4.2
Elasticsearch version: 7.6

Any help is much appreciated!!

Answer 1

By the looks of it, you have some numerical (int or decimal) attribute which is set to be searchable and causes the error as it would expect a number to be provided.

You can:

1. Check all your searchable attributes and make those which have a numerical data type to be set as not searchable.
2. If you want to keep the attribute as searchable, then enable coerce on those fields in ES document mapping.
