The consonantal representation of the lexeme of a word occurrence in Hebrew script.
This feature is present on objects of type word.
Only the consonants of the lexeme are present: no vowel pointing and no other diacritical marks.
It is difficult to enter Hebrew text. One of the handiest ways to get Hebrew text into a query is to copy and paste it from some other Hebrew text, e.g. from the SHEBANQ.
You could try to copy and paste Hebrew text into a word processor, then remove all diacritics, and paste the result into your query as a value for lex_utf8.
