Systems and methods for searching databases using graphical user interfaces that include concept stacks

摘要

Systems and methods for searching databases using graphical user interfaces that include concept stacks are disclosed. A method includes providing for display graphical user interface comprising a query building canvas. The graphical user interface includes concept stacks that include stacked concept nodes associated with query terms that are joined with Boolean ORs. The concept stacks are connected by a conjunctive proximity connector that joins the query expressions associated with each concept stack. The graphical user interface includes a connector node that includes a graphical indication of the conjunctive proximity connector. The method further includes generating a search query to include query expressions associated with the concept stacks that are connected by the conjunctive proximity connector. The method further includes searching the database using the search query to identify the result set of documents.
