In the paper some issues connected with indexing documents in the Polish language are discussed. Algorithms for stemming and part of speech tagging, important in the process of text analysis and indexing are shortly described. Next their suitability to the Polish language, which has a very extensive inflection, is discussed. The usefulness for stemming and part of speech tagging of large dictionaries with inflected forms, like WordNet and open-source dictionary of Polish language is also described. Two dictionary structures enabling effective word searching are presented. In the final part, some tests of implemented two dictionary structures are described. Tests were made on the six actual and three crafted artificial texts. At the end conclusions of performed tests are formulated. (original abstract)
