I'm with Umbraco 12, I'm trying really hard to search for content with a specific value with wildcard. All the documentation / posts I stumble upon are outdated.

What I need : Find any "recipe" document that has either nodeName or shortDesc field containing the filter text in parameter.

Here's my code :

var results = index.Searcher.CreateQuery("content")
                        .NodeTypeAlias("recipe")
                        .And(q => q.GroupedOr(new[] { "nodeName", "shortDesc" }, filter))
                        .Execute();

that seems to work but only IF the filter value matches exactly the document value.

I then tried that :

var results = index.Searcher.CreateQuery("content")
                        .NodeTypeAlias("recipe")
                        .And(q => q.GroupedOr(new[] { "nodeName", "shortDesc" }, filter.MultipleCharacterWildcard()))
                        .Execute();

It works but only as a wildcard at the end ot the beginning (example: for the word "ceiling", searching for "ceil" would find it, searching for "ling" would not)

Anyone could give me a working example on how to do this? Or point me to the right up to date documentation?

Thanks
