Spellcheck + dictionaries

Proposal:

Please consider checking words through SUGGEST first using the standard dictionary of Russian or any other language and first suggesting substitutions from there, and only then looking for them in the index. Optional, of course.

Yes, for academic texts where there are no errors, the current implementation is quite suitable. But for the forum, it doesn't always work well. For example, the word “pamagite” is replaced by “pomagite”, “pamagiti”, “pamagitya”, “poamagite”, etc.

This will also be good for the words in the query that are not on the site, but there may still be useful information in the query.
