The importance and size of Web search engines is increasing daily. Information retrieval
systems based on a single centralized index present several problems, which lead to the …

The increasing number of documents that have to be indexed in different environments,
particularly on the Web, and the lack of scalability of a single centralised index lead to the …

The increasing number of documents to be indexed in many environments (Web, intranets,
digital libraries) and the limitations of a single centralised index (lack of scalability, server …

The amount of information available over the Internet is increasing daily as well as the
importance and magnitude of Web search engines. Systems based on a single centralised …

Large document collections are increasingly available over the network. In order for users to
access these collections, information retrieval systems must provide coordinated …

We simulate different architectures of a distributed Information Retrieval system on a very
large Web collection, in order to work out the optimal setting for a particular set of resources …

Searching the web is critical to the Web's success. However, the frequency of searches
together with the size of the index prohibit a single computer being able to cope with the …

In this study, we present the analysis of the interconnection network of a distributed
Information Retrieval (IR) system, by simulating a switched network versus a shared access …

Distributed information retrieval (DIR) is a model enables a user to access many searchable
databases reside in different locations. DIR is more complex than the centralized information …

The performance evaluation of an IR system is a key point in the development of any search
engine, and specially in the Web. In order to get the performance we are used to, Web …
