The message says "Enable internal query rewriting. Some search backends can rewrite the query into one its thinks gives better results, such as correcting spelling errors."

Please change "its thinks" to "they think". If the subject were singular, it should be written "it's" in any case, but it's "some search backends", which is plural.
