In this paper we present a first analysis towards better understanding of the query constraining aspects of knowledge, as expressed in the most used public medical bibliographic database MEDLINE. Our results indicate, possibly not surprising, that new terms occur, but also that traditional terms are replaced by more specific ones or even go out of use as they become common knowledge. Hence, as knowledge evolve over time, search methods may benefit from becoming more sensitive to knowledge expression, to enable finding new, as well as older, relevant database contents.
在本文中，我们首次进行了分析，旨在更好地理解知识的查询约束方面，这在最常用的公共医学文献数据库MEDLINE中有所体现。我们的结果表明，新术语出现了，这或许并不令人惊讶，而且传统术语被更具体的术语所取代，甚至随着它们成为常识而不再使用。因此，随着知识随时间演变，搜索方法可能会受益于对知识表达更加敏感，以便能够找到新的以及旧的相关数据库内容。
