![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
The Semantic Index Field form enables you to define a semantic index field for use in an AI Search semantic index configuration.
To learn about defining and modifying semantic indexing settings for an indexed source, see [Configure semantic indexing settings for an indexed source](https://servicenow-prod.fluidtopics.net/FCz4vqBVFx_rBmrku4r_XQ "Specify the semantic indexing configuration settings you want to apply when AI Search indexes records from your indexed sources."). For details on semantic index configuration fields, see [Semantic Index Configuration form](https://servicenow-prod.fluidtopics.net/BhjiBfirPIjoYXrFfrMjNg "The Semantic Index Configuration form enables you to define semantic indexing settings for an AI Search indexed source.").  
Note:  
This form is only available when the AI Search Semantic Controller plugin (com.glide.ais.semantic_search) is active on your instance. To activate this plugin, your instance must have at least one [ServiceNow Otto® application](https://www.servicenow.com/docs/access?context=platform-now-assist-landing&version=australia&pubname=australia-intelligent-experiences&ft:locale=en-US) installed.
