Filtering files by source with Automator
Based on your comment, 'I want to say "PDFs downloaded from URL contains "bank name" move to folder "banking"', here is how I'd do it in Automator:

In Automator, create a new Workflow, adding the following Actions:

Find Finder Items, with settings:


Search [Downloads]
[All] of the following are true
[Kind] [is] [PDF]


Run Shell Script,  with settings:


Shell [/bin/bash]
Pass input [as arguments]
Replace the default code with the example code below.

for f in "$@"; do
    [[ $(mdls -name kMDItemWhereFroms "$f") == *bankname* ]] &amp;&amp; echo "$f"
done

Note: In the code above, replace "bankname" in *bankname* with the actual bank name in the URL.


Move Finder Items, with settings:


To [Banking] &nbsp;&nbsp;[] Replacing existing files
