635 Park Ave

Look under 633 Park

Shows up in the app.

Hmmm. From a regular desktop browser, on the SE home page, if I type '635 Park' into the little search bar in the upper right, it returns a message "No results for "635 Park" in NYC or NJ". This is whether I'm logged in with my ID or not. If I search '635', I get a list of buildings, and 635 Park is not in the list. I get that they may be showing only buildings with current listings or recently closed sales, and this is one of those 'they only leave in a box' buildings, with few units and very low turnover, but really..... ?? Or have I been blocked by the UES co-op cabal from researching certain buildings?

searching for 633 doesn't get me anywhere either...

Use Google Search

Streeteasy search is not that good. I am sure you see that for discussion search.

Finally got it via 300's search. Thank you!

Something is clearly broken with SE's search, but the people who are looking to buy at 633/635 probably aren't using SE anyway.
