J.  aAn information retrieval system based on multiple portletsbcommunication between its components.h[electronic resource]  c2021  aABSTRACT. Information retrieval systems built with a service-oriented architecture have numerous advantages, and portlets are a key technology to implement services which interact with each other in the presentation layer. This work presents an efficient approach for the communication between the components of an information retrieval system based on multiple portlets in a single user interface. It also presents the architecture and the main methods of the system implemented as a case of use for this approach. It is shown that the proposed solution yields the best inter-portlet communication mechanism in each situation, while possessing the ability to deliver aggregated search and superior user experience.  aUser interface  aAggregated Search  aElasticsearch  aInter-Portlet Communication  aInterface ao usuário  aJava Portlet Specification  aLiferay Portal  aPortal Technology  aSearch Engine  aService-Oriented Architecture  aSistema de recuperação da informação1 aBARBEDO, J.
