 Title: Effectiveness of Title-Search vs. Full-Text Search in the Web Authors: Shoval, PeretzKuflik, Tsvi Keywords: IndexingInformation retrievalPrecision of Search ResultsSearch EnginesTitle SearchWeb Search Issue Date: 2004 Publisher: Institute of Information Theories and Applications FOI ITHEA Abstract: Search engines sometimes apply the search on the full text of documents or web-pages; but sometimes they can apply the search on selected parts of the documents only, e.g. their titles. Full-text search may consume a lot of computing resources and time. It may be possible to save resources by applying the search on the titles of documents only, assuming that a title of a document provides a concise representation of its content. We tested this assumption using Google search engine. We ran search queries that have been defined by users, distinguishing between two types of queries/users: queries of users who are familiar with the area of the search, and queries of users who are not familiar with the area of the search. We found that searches which use titles provide similar and sometimes even (slightly) better results compared to searches which use the full-text. These results hold for both types of queries/users. Moreover, we found an advantage in title-search when searching in unfamiliar areas because the general terms used in queries in unfamiliar areas match better with general terms which tend to be used in document titles.
