Hi would it be possible to add a custom API call for SolarCoin to specifically search on the tx-comment field?

We are now publishing solar PV generation data to the SolarCoin blockchain (example TX https://chainz.cryptoid.info/slr/tx.dws?91722ba414480aebe78680c68a1594ed948cce59c4aa0ebbbc4728d7de8ef78f.htm) and ideally need to be able to search on and parse the UserID.

We can currently only find the first 5 results on the current searc.
Thanks.
