To find all forms of a word, type its base form in the Lemma box. The base form is Nominative singular for nouns (except for pluralia tantum as очки, сливки, прятки or шахматы), Nominative masculine singilar for adjectives and Infinitive for verbs.

If you need to find an exact form, use the Wordform box.

Additional options with search operators are available for the Lemma and Wordform input boxes.

You can search for several words simultaneously. You need to type both words in the Lemma box, separated by the OR sign with spaces ( | ): мама | папа. The same came be done in the Wordform box.

This operator as well as the minus operator can be also manually included into the boxes of additional, grammatical or semantical tags.  For example, the query конечно -bmark | -amark will yield all examples with the word конечно which is either preceded by a space and not a punctuation mark (С учётом их природных данных и склонностей конечно.), or followeb by a space and not a punctuation mark (Конечно же,), or both (И конечно же). 

If you type a word into the Lemma box of the Lemma and tags search, all its forms will be found. You can limit your search to a specific form using quotation marks or type it into the Wordform box. This may be useful for complicated queries, e.g. when searching for phrases or using the minus ( - ) operator. For exanple, the easiest way to find out which verbs occur wth the phrase под мышкой, the easiest is to put мышкой under quotes: V; distance 1 from под; distance 1 to 3 from "мышкой". 

You can exclude the wordforms you do not need from the search results. To do that, type the base form into the Lemma input box, then type the minus sign followed by the wordform you do not needed, without a space and in quotation marks. For example, searching for the forms of the verb прочить in the disambiguated part of the main corpus yileds many examples with the word прочь (as in Прочь отсюда! ) which is a homonym to the imperative form of this verb (as in Не прочь меня в начальники).  To get rid of these examples, you can type прочить -"прочь" (but bear in mind that in this case the imperative forms will not be found either).

To exclude a form that you do not need you can also use the minus sign in the Wordform box, putting it before the form.

You can remove as many forms as you need. In the example with the verb  прочить, you would not only need to remove the form прочь, but also the form прочен, which is also homonymous because it could be a participle of прочить or the short form of the adjective прочный: прочить -"прочь" -"прочен".

If a lemma is specified as a wildcard with an asterisk, the minus sign (without quotes) can be used to exclude unnecessary lemmas. For example, the query *вед -швед will find all the lexemes ending in -вед such as искусствовед, but not швед.

The minus operator can also be used with the grammatical features or additional tags. To do that you will need to find the name(s) of the tag(s) you do not need. You can look them up in the list or find them through the popup menu. After you found the name of the tag, you can include it into the corresponding box of the query preceded by the minus sign. The priority of the operations NOT, AND, OR and brackets is usual. Accordingly, by adding a minus sign (NOT) to the query string before the brackets, you exclude everything in brackets, by adding a minus before the token, you exclude only the nearest token.
