The data environment is represented as a tree\u2010like structure containing over 15,000 unique databases and approximately 100,000 total leaf nodes. The search modes consist of varying degrees of browse and search, from a global search at the root node to a refined search at a sub\u2010node using dynamically\u2010calculated inverse document frequencies (idfs) to score the candidate databases for probable relevance. Our findings indicate that a browse plus search approach that relies upon localized searching from sub\u2010nodes in this environment produces the most effective results.<\/jats:p>","DOI":"10.1002\/meet.1450390115","type":"journal-article","created":{"date-parts":[[2005,1,31]],"date-time":"2005-01-31T12:51:27Z","timestamp":1107175887000},"page":"130-139","source":"Crossref","is-referenced-by-count":0,"title":["Global vs. localized search: A comparison of database selection methods in a hierarchical environment"],"prefix":"10.1002","volume":"39","author":[{"given":"Jack G.","family":"Conrad","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joanne Smestad","family":"Claussen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Changwen","family":"Yang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,1,31]]},"reference":[{"key":"e_1_2_12_2_1","first-page":"169","volume-title":"Proceedings of the Sixth Text REtrieval Conference (TREC\u20106)","author":"Allan J.","year":"1997"},{"key":"e_1_2_12_3_1","first-page":"58","volume-title":"ACM Communications","author":"Belkin N.
