Evaluation
: Due to the broad nature of my topic, the number of retrieved documents is rather high. Because the records are displayed in order of decreasing revelancy, I am able to assess that the retrieval precision is relatively low, dropping off sharply after the first 100 hits or so. To increase the precision I can start the search with the most specific facet in my topic (lifelong learning), then narrow down the results further using Boolean operators (AND public libraries AND resource or program NOT statistics). Non-subjects attributes can also be used to limit the search, for example document type (full-text), language (English), and publication year (after 1999).
