Hello.
I was trying to help someone on a previous post, so I started doing some syntax search and I was "blocked" by one problem while searching in A-F in Hebrew.
I want to find lexeme cognates between a predicate and a object. See the search query I built:

Well I could find some results. For example, it retrieves me Gen 12:3 "I will bless those who bless you." However it is not accurate, it does not retrieve all the occurrences. A clear case, which should be part of the result but does not show up is in Gen 37:9 "he dreamed a dream again." Notice that A-F takes 2 lexemes for "dream." The verb is a lexeme and the noun is another. So, in this case, how can I find a cognate even when the lexeme is different, but at the same time from the same Head Word? Does any one have an idea if this is possible? I must be missing something in the search.
I thank in advance for any help.
Blessings,
