The Valuer algorithm applies NLP "Natural Language Processing" to the free form text in your search queries. This is similar to other search engines, such as Google.
The Valuer algorithm works by identifying company descriptions that are most relevant to your search, both by looking for relevant keywords, but also semantics that suggests a similar focus within the company descriptions.
Your search is in simple terms used as an ideal company for what you need to find and the algorithm tries to find the most similar companies to that definition in our database.
