information retrieval system (DB) (IRS)

Information Retrieval(IR) is the recovery of information. The corresponding systems are the Information Retrieval Systems(IRS). IR systems provide for the retrieval and restoration of stored information. These functions are also performed by search engines.

Search engines are essentially concerned with collecting and recording information, analyzing it, indexing it, and presenting the stored information. The main functions of IR systems relate to indexing. For this purpose, the data is structured so that it can be presented during a search process for the keywords. The information retrieval depends on the indexing function, the number of documents, the search queries and some other parameters.

The actual query is performed using database languages. The search words entered are compared with the index and the results are output as a result page in a search engine-specific manner, i.e. according to certain parameters and their weighting.
