Manage company name extraction in SharePoint Server
APPLIES TO: 
2013 2016 2019 Subscription Edition 
SharePoint in Microsoft 365
The search system can extract company names from content. The following conditions must be met before company names can be extracted:
The managed property setting Company name extraction must be enabled on the managed property that you want to extract company names from. Typically, this is a managed property that you expect to contain these entities, such as the managed properties Title or Body. Company names are extracted from the full contents of the managed property they are associated with, even if sections in those contents are tagged as <no index>.
The name of the company that you want to extract should either already exist in the prepopulated company name dictionary or it should be included in the Company Inclusions list.
A full crawl must be completed.
For example, if a company name is found in the body of a document, company name extraction is enabled on the managed property Body and a full crawl has been run, the company name is extracted and mapped to the managed property companies. You can then use the companies managed property to create refiners based on the extracted company name in the Refinement Web Part on the search results page.
There is a prepopulated dictionary for company name extraction which includes a large number of company names. You can add additional company names to be extracted or prevent particular company names from being extracted using the Company Inclusions or Company Exclusions lists.
This article explains how to maintain these lists. It does not cover how to enable a managed property to use company extraction. For more information on how to enable company extraction on a managed property, see Manage the search schema in SharePoint Server.
