Custom text analyzer for url encoded logs


I am ingesting log files to Elasticsearch(v7.17.1) and using Kibana(v7.17.1) to search the logs.
Some of my log lines have url encoded strings like below. I am trying to use custom text analyzers to be able to search using the url or other query params. But because of the url encoding chars like %3D, %5E, etc, I have to use wildchars around my search texts which slows down the searching drastically. Please suggest any built-in or custom analyser which can help to get url decoded tokens. Thanks.
