The (standard) Boolean model of information retrieval (BIR)[1] is a classical information retrieval (IR) model and, at the same time, the first and most-adopted one.[2] The BIR is based on Boolean logic and classical set theory in that both the documents to be searched and the user's query are conceived as sets of terms (a bag-of-words model). Retrieval is based on whether or not the documents contain the query terms and whether they satisfy the boolean conditions described by the query.
