Contextuality and Ranking

ContextualWeb uses algorithms inspired by the human brain to form a huge contextual network based on the world wide web. This network captures connections between entities such as persons, places, things and events. When a search query is made, ContextualWeb predicts its relevant context. Knowing the correct context of the search query allows us to provide the most accurate and relevant search results.

Our results are superior to those provided by other popular data providers like Swiftype and Webhose ( based on ElasticSearch and Solr) as these solutions are intrinsically textual and have no real understanding of the context of the search query.

Related Search

Our unique Related Search feature provides a list of relevant queries for a given search query organized by relevance. This highly dynamic list can help you in refining your search to get deeper insight into the topics you are researching.

You will find ContextualWeb’s related search significantly more relevant & authentic than Bing or Google’s suggestions. The reason for that is simple: since Bing and Google are commercially driven, their related search results are biased towards the ones that have more potential to generate the search engines more clicks. In contrast, our related search feature brings you a loyal snapshot of the world wide web as it truly is.


We’re committed to offering the most affordable custom search engine on the market. Our basic plan suits most developers and startups and includes 10,000 free request per month. Companies and enterprises with higher volume needs can choose more sophisticated plans that offer millions of requests per month. We charge by number of requests without any limitation and restriction.

Our purpose is to make a dent in the search industry by making it accessible and affordable to all developers and companies.
