In this group of fields, you can set one or more basic text parameters to customize a subcorpus. If you specify several different parameters ("Date of creation", "Title", "Genre", etc.), only documents for which the values of all parameters are true will be found (logical AND). If you specify several values of one parameter (Genre: epistle, act, etc.), all contracts and all memoranda will be found (logical OR).

For some search fields there is a list of values available. If there is no list of values available, you must specify the parameter by entering all or a few words from the keyboard (typically in original Cyrillic).

The parameter Single version per text allows us to obtain a sample that does not include different versions of the same work. The choice of the “main” text is largely arbitrary (e.g., for the Tale of Bygone Years the version of the Hypatian copy is chosen, and for Theodosius' Vita the later version in the Patericon). This parameter can be used separately or together with other fields such as "Text or group of texts" or "Title". If a user selects the Tale of Bygone Years (Hypatian copy) and ticks the checkbox Single version per text, this text will be included in the subcorpus. However, if the user chooses Tale of Bygone Years (Laurentian copy) and ticks the same checkbox, nothing will be added to the subcorpus as the conditions are exclusive. If the user selects the group of texts Smolensk Letters of the 13th-14th centuries and ticks the checkbox, only those letters from the group of text that have been marked as "main" will be included in the subcorpus.
