Hi Folks

I was fixing a bug which came through the upgrade from Spring 2.5 to Spring 3.0.  
Now before in Spring 2.5 we had custom method from a repo that extended the ElasticsearchRepository interface, and in the method we passed some parameters which were escaped beforehand.For example  
searchItemsBySomeParameter(  
projectId, ElasticMyClass.escape(searchParam), language, dbPageable);

the ElasticMyClass.escape escaped special characters like /? etc. It was working fine.  
After the upgrade to Spring 3.0 it startet giving problems each time we tried to search with special character, the i simply removed the ElasticMyClass.escape method, and now it seems to work.My question is ,i know that Spring 2.5 used 7.xx Elastic client, whereas Spring 3 uses Elastic 8 something client.I tried to go through the Release notes to find what did change, but i could find anything, does anybody know what changed and in which version so that escaping is no longer needed ?

Thanks
