There is no entry in the $TCA array for the table "index_stat_word". TYPO3, v.11.5. Indexed search

Question

I need a help please. TYPO3 v.11.5. I'd like to get data from table index_stat_word (indexed_search):

page {
    10 = FLUIDTEMPLATE
    10 {
        dataProcessing {         
            20 = TYPO3\CMS\Frontend\DataProcessing\DatabaseQueryProcessor
            20 {
                table = index_stat_word
                select {
                    selectFields = word, COUNT(word) AS word_count
                    groupBy = word
                    orderBy = word_count DESC
                    max = 4
                }  
                as = mostPopularWords
            }
        }
    }
}

I have an error:

There is no entry in the $TCA array for the table "index_stat_word". This means that the function enableFields() is called with an invalid table name as argument.

The table "index_stat_word" is present and complete.

Thank you for the answers.
