Is there a format to search by address?

There’s no specific format, but keep in mind that addresses can be entered in various ways.  Street can be spelled out or abbreviated.  So try different formats.  In recent years, the County Clerk has begun indexing the Property Address, but that hasn’t always been the case.  So if you don’t get any results by entering the address in Advanced Search, try using QuickSearch (the default).  QuickSearch takes advantage of OCR full text.  By looking at the full text of each document, you may have more luck, particularly with addresses.  Also try using quotes to perform an EXACT SEARCH.  Such as “100 main”
