The problems of construction and integration of information retrieval systems with corporate information systems are considered. A model of information query and search results for the database and file data stores is described. The task of information retrieval is represented as the interaction of domains using an adapter. The task of the adapter is to convert the information needs, expressed in the language of a particular document into a search query, presented in the language of the information retrieval system. The representation of search queries in the language of the search engine assumes the following order of operations: the definition of the target entity, the conversion of the criteria specified by the user, and the addition of criteria specified by the source system. An algorithm for the order of the transformation is proposed in the general form.
The implementation of the proposed model in the PHP framework of the web portal based on the Apache Solr search engine is considered.
