Web ontologies are structural frameworks for organizing information in semantics web and provide shared concepts. Ontology formally represents knowledge or information about particular entity as a set of concepts within a particular domain on semantic web. Web ontology helps to describe concepts within domain and also help us to enables semantic interoperability between two different applications by using Falcons concept search. We can facilitate concept searching and ontologies reusing. Constructing virtual documents is a keyword based search in ontology. The proposed method helps us to find how search engine help user to find out ontologies in less time so we can satisfy their needs. It include some supportive technologies with new technique is to constructing virtual documents of concepts for keyword based search and based on population scheme we rank the concept and ontologies, a way to generate structured snippets according to query. In this concept we can report the user feedback and usability evolution.
