FIELD: computer equipment.

SUBSTANCE: invention relates to computer engineering. Disclosed is an information retrieval method implemented in a corporate information retrieval system configured to extract results from a plurality of different sources, comprising steps of receiving a request at an input; at the output, this request is issued in a set of different sources, wherein it is characterized by a hierarchical multi-tree list view of search results in form of one or more sets of related graphs, which nodes do not contain cycles, but can have duplicates and intersections with other sets or branches, wherein there can be a non-unique path, characterized by a sequence of nodes, from root to node, tree roots have a list representation and can be opened if necessary or interacting with the user interactively; includes execution of search requests; performing search query analysis by means of morphological analysis; accessing a search index database through a corporate information retrieval system and extracting search results therefrom; generating search results using a corporate information search system based on the right of the user making the request, and rights associated with the source information; filling a search index base; using information on document structure; aggregation of obtained information from files into documents, wherein files are considered as version of document; merging, via a corporate information search system, versions of files into a document for constructing a common index; finding, through a corporate information retrieval system, documents with similar structural data from meta-information for subsequent output of found information to a user in the presence of necessary rights; combining these documents through the corporate information retrieval system into higher-level structures, such as "project", "direction"; display when searching results in the form of "project", "direction".

EFFECT: technical result is possibility of searching information with provision of information aggregation, information presentation form and compliance with information security requirements when providing access to documents.
