Technical Prerequisites

Before going further, ensure your technical team completed the pre-requisites.

Installing the module

The module responsible for neural search is smile/module-elasticsuite-neural-search and this module is not part of the standard Premium package. You’ll need to install it manually prior going further.

Enabling neural search feature

You can head to Stores > Configuration > ElasticSuite > Neural Search

Parameter	Default value	Description
Enable Neural Search	No	Set this to “Yes” to enable the neural search feature
Model Type	Pre-trained	⚠️ For now, only Pre-Trained models are supported
Pretrained Model		A list of pre-trained models available in Opensearch. The default one is recommended.
Compute embeddings from a specific store	No	When using a LLM capable of dealing with multiple languages, you can choose to compute the embeddings from a particular store view and use them for all the other languages. That’s particularly valuable if you have a store view which is greatly contribued. It can then be used to leverage the data of the other stores.

Enabling attributes for Neural Search

Enable the “Use for Vector Search” option on the attributes you plan to use with Neural Search. Refer to the attribute configuration page to do so.

Configuring neural search feature

You can head to ElasticSuite > Search Relevance > Neural Search

Parameter	Default value	Description
Use vector search as a fallback when there is no search result.	No	We recommend to set this to “Yes” to use the neural search as a fallback
Use vector search in spellchecked	No	When set to yes, the neural search will be used as part of the spellchecking. We don’t recommend to use this.
Use vector search in exact matches	No	When set to yes, the neural search will be used as part of the exact matching. We really don’t recommend to use this.
K Value	100	We recommend to let this value to the default one.
Use Min Score	No	We don’t recommend enabling this
