Does Wordlist endpoint make searches only from ODE?

Hi @AmosDuveen

Hope u r well!

This time I wanted some clarity on whether wordlist endpoint made searches from ODE alone or if it used the data offered by NOAD as well.

As suggested by @annarita__amenduni in her post https://forum.oxforddictionaries.com/api/discussion/192/how-do-i-look-up-phrases-using-the-api#latest, I made a search for a list of all words having lexicalCategory=idiomatic using https://od-api.oxforddictionaries.com:443/api/v1/wordlist/en/lexicalCategory%3Didiomatic?word_length=%3E1%2C&exact=false. It returned 8818 results but upon investigation, I figured it still misses out on many. The uniqueness in the missing results (at least the ones I checked) is that they all belong in NOAD only...hence my question. I can't say for sure, at least not now, but the number of missing results may be in thousands. Here are some examples:

a peg to hang a matter on
a prophet is not without honor, but (or save) in his own country
around (or round) the clock
as cold as ice (or stone or the grave, etc.)
as plain as the nose on one's face
at daggers drawn
a/the lesser evil (or the lesser of two evils)
at risk to oneself (or something)
a wrench (or monkey wrench) in the works

Eagerly looking forward to your reply! If what I'm inferring is correct and if no solution is offered anytime soon, I would have to go through a lot of manual exercise.
