English abstract

The Web of Science interface counts at most 100,000 retrieved items from a single query. If the query results in a dataset containing more than 100,000 items the number of retrieved items is indicated as >100,000. The problem studied here is how to find the exact number of items in a query that leads to more than 100,000 items. One way to achieve this objective is presented. The retrieval of the entire scientific production from the United States in a specific year (2007) is counted and an advanced search strategy is designed. Different sections of items can be retrieved using the Source field of the database. A Boolean statement was created with the aim of eliminating overlapped sections and improving the accuracy of this search strategy.

La interfaz de la Web of Science permite recuperar como máximo 100.000 registros en una búsqueda simple. Si el resultado de la búsqueda tiene más de 100.000 registros, el número de registros recuperados se indica como >100.000. En este artículo se presenta una forma de encontrar el número total de registros en una búsqueda que supera los 100.000 registros. Concretamente, se contabiliza la producción científica total de los Estados Unidos en un año específico (2007). Se diseña una estrategia de búsqueda avanzada para recuperar conjuntos diferentes de registros usando el campo Source
