A romaji the site can't recognize

The only entries that I cannot get to work here are the dzu  or tzu or zu form of tsu.  -> つ to づ.  For example; katadzukete (or) katatzukete  (or) katazukete.  None of them are recognized by your dictionary, and I cannot seem to find a way get around it when I need to insert the romaji rather than the kana.

Another example is 

搭乗手続き  - とう じょう·てつづき; 

I can enter the kanji 搭乗手続き with results, and I can enter the kana とうじょう·てつづき

with results.   However when I enter the romaji

toujoutetsutzuki  (or)  toujoutetsudzuki  (or)  toujoutetsuzuki it comes up as an error.

Just curious what I am doing wrong.

Thank You

The convention on this site is to use du for づ. The reason behind this is to distinguish it from ず(zu), and it is the same as how you type the hiragana character.

So to search for 続く「つづく」in romaji, you would enter tsuduku.

THANK YOU SO MUCH!!!!   This has been driving me crazy for months!   I will do as you say, and thank you again!
