Proposal of a model of searching over NoSQL databases working with indeterminacy

The paper is devoted to identification of indeterminacies related with the construction and operation of NoSQL databases and which have a significant impact on the querying possibilities. The problematic issue of NoSQL databases has been selected for its turbulent development of this type of data sources, which are characterised by their diverse architecture, and frequently vague structure of the stored records and, last but not least, a distributed character of this data source. The objective is to identify potential occurrence of indeterminacies and to propose a model which will work with these indeterminacies effectively.
