Abstract
Several public Search Engines exist of which their coverage and response time differ.
Now which one does perform best under the present connectivity? This study aimed at
investigating the information indexing and retrieval effectiveness and efficiency of ten
selected search engines under different connection speeds at two University Libraries
namely Sokoine University of Agriculture (SNAL) and University of Dar es salaam
Library (UDSM).
Google followed by Yahoo outnumbered all the other eight-search engines in terms of
relevance, precision, and responsiveness. In terms of other features such as phrase
searching, simple and natural language interface, high quality of display results, these
search engines were the best. MetaSearch engines especially MetaCrawler performed
the worst in indexing and retrieving scientific literature particularly at UDSM library.
There was a significant difference of search engines performances between the two
connection speeds. User information searching skills was notably poor calling an action
from information professionals.
