Synonyms and alternative expressions

[janbarasek]

As you rewrite the query, add synonyms and similar variants to each word.

Through the implementation of the interface, the user can influence the rewriting of synonyms (for example, by language), or add his own dictionary of similar words.

As part of the transcript of the query, it should be possible to insert a translator that will try to search for words in other languages as well. If there is an ITranslate from Nette, inject it automatically.
