Hello! I am trying to use this endpoint: [PatronSearch](https://documentation.iii.com/polaris/PAPI/current/PAPIService/PAPIServicePatronSearch.htm?Highlight=ccl)

I am retrieving a large amount of patrons (over 100,000), and there seems to be a hardcoded limit of 100,000. I plan to separate my data fetches out using the registration date to accommodate this, but I cannot figure out how the URL search param (it’s in CCL format which I am unfamiliar with) should be formatted. The endpoint will not accept:

/protected/[1](https://documentation.iii.com/polaris/PAPI/current/PAPIService/PAPIServicePatronSearch.htm?Highlight=ccl#)/{AccessToken}/search/patrons/boolean?q={ccl}  
Where ccl = REGD%3D2026-01-01 or REGD%3D20260101

The above is simplified from my actual query for testing. Does anyone know how the date should be formated?

Figured it out by looking at how request is formatted via the search in LEAP. Should be:

REGD%3D%222026-01-01%22

The date has to be surrounded by encoded qoutes. A range can be done like this:

REGD%20%3D%20%222026-09-14%22%20-%20%222026-09-14%22%3B
