The standard search box in the top bar of the XNAT application can help you quickly find the data element you want to work on.
Many experienced XNAT users quickly adopt this as one of their favorite shortcuts for navigating their data. However, its behavior differs from the now-ubiquitous Google-style search boxes that proliferate in the web today. Here's a quick introduction to how XNAT Search works.

Alias = [entry], or
Keywords LIKE [entry]
If you send an entry that finds multiple matches, you will get a disambiguation results page. For example, searching for "001" in XNAT Central yields the following results:
