Pavel, I think there is no single way to implement this. Some ideas that might be helpful:
1. Consider adding additional terms while indexing. This assumes conversion of Russian text to both "translit" and "wrong keyboard" forms and index converted terms along with original terms (i.e. your Analyzer/Filter should produce Moskva and Vjcrdf for term Москва). You may re-use the same field (if you plan for a simple term queries) or create a separate fields for the generated terms (better for phrase, proximity queries etc. since it keeps the original text positional info). Then the query could use any of these forms to fetch the document. If you use separate fields, you'll need to expand/create your query to search for them, of course. 2. If you have to index just an original Russian text, you might generate all term forms while analyzing the query, then you could treat the converted terms as a synonyms and use the combination of TermQuery for all term forms or the MultiPhraseQuery for the phrases. For Solr in this case you probably will need to add a custom filter similar to SynonymFilter.
