muliselect attributes are not being indexed

[superdav42]

Preconditions

Magento Version : 2.2.5

ElasticSuite Version : 2.5.14

Environment : Developer

Third party modules : AvS_DisableModules Cart2Cart_PasswordMigrationToMagento2 Infortis_Infortis Infortis_Brands Infortis_Cgen Infortis_Dataporter Infortis_Base Infortis_UltraSlideshow Infortis_UltraMegamenu MSP_Common MSP_DevTools Aheadworks_Autorelated BrainActs_RewardPoints Infortis_Ultimo Aheadworks_Sarp Mageplaza_Core Mageplaza_Smtp Pmclain_AuthorizenetCim

Steps to reproduce

1. Create a muliselect attribute
2. Add some values
3. Add some products with the value
4. Perform site search with query equal to one of the multiselect values

Expected result

Products with multiselect values select show up in site search

Actual result

The product does not show up

This is probably related to magento/magento2#13972 but the fix for that did not solve it with elasticsuite. I dug around a while but couldn't find out how the data for attributes is retrieved by the indexer in elasticsuite, it doesn't seem to use the same DataProviders.

Hello, it's working like a charm on our demo env : http://demo.magento-elastic-suite.io/index.php/catalogsearch/result/?q=polyester ("polyester" is a value of the "material" attribute which is a multiselect)

So I strongly suspect a misconfiguration by your side, or a side-effect due to third party modules.

Can you please ensure that :

• your attribute is set as "Used in search"
• your catalog is reindexed

Turns out it was a problem on our site because we were using a custom backend model for our multiselect attribute. I made a PR which should help others in the future #1017

So I suppose we can close this one in favor of #1017
