(via search templates and forms)
The combination of search templates together with a forms based interface is user-friendly option which enables inexperienced users to rapidly construct sophisticated search strategies without training. When constructing templates system designers constrain free form user input via selection of common queries to be supported in advance. When a user enters terms into a form they can be combined into a logical search statement in one of two main ways:
- Implicitly – via automatic use of Boolean ‘AND’ operators between fields in the form
- Explicitly – where users select logical operators to be used between a form’s fields via a menu
The advantage of the latter option is increased flexibility; the disadvantages are the same as with logical statements in general.
