A system for information retrieval accessing any number of search engines over a distributed network or local network is presented. The system includes one or more pre-built ontologies or lexicons, representing areas of knowledge. The system includes a settings panel where searchers can preset default languages, default ontologies, and target search engines. The system includes an application that receives a variety of searcher input from a user interface such as a spinning wheel, or from a scrolling list. Through such selections, the application subsequently builds a Boolean search engine string of terms. The Boolean search string is then passed to the target search engine for retrieving semantically accurate search results. The Boolean search string provides a tight range on the search parameters and thereby delivers higher quality results that are more precise.
