Exact Match Syntax in Legal Information Retrieval

The following is a basic concept of Exact Match Syntax in relation to information retrieval. In addition to this, Exact Match Syntax may be applied to legal texts, including case law, legislation and scholarly works. Exact match syntax for electronic matching of terms in non-displayed indexes requires that terms associated with documentary units match exactly the requirements of the search statement. Most often exact match syntax is implemented using boolean operators; it is often called boolean syntax. Note however that the requirements of the boolean or operator permit terms linked with or to be either present or absent. Only documentary units whose terms match search statements exactly (within the parameters provided by search syntax options such as truncation, proximity ranges, and stemming) are retrieved.
