In Umbraco, how to handle tag datatypes with Examine? - asp.net-core

Question

I have made a search page using Examine which for the moment works fine and as intended (still needs to get paging sorted...), but I have run into an issue. I also want the page to function as a related tags page, as in an article can have several tags, and if you click a tag you can see related articles with the same tag. Pretty basic stuff. Only I have found out that Examine cant really handle tag data types because as I understand they are stored in a comma delimited list, something Examine cant handle in this case. I have searched around and found only a few hints of others having the same problem, one with an actual solution but that sadly no longer works in Umbraco 10: Umbraco - Using Examine to search Umbraco.Tags
Also found this more recent one, but kind of a dead end: https://our.umbraco.com/forum/umbraco-8/98761-how-to-match-tags-in-examine-in-v8-theyre-now-stored-as-a-json-string-array
So yeah, what the heck do I do?
For good measure here is my examine code:
#{
Layout = "master.cshtml";
var searchQuery = !string.IsNullOrWhiteSpace(Context.Request.Query["q"].ToString()) ? Context.Request.Query["q"].ToString() : "";
var tags = !string.IsNullOrWhiteSpace(Context.Request.Query["tags"].ToString()) ? Context.Request.Query["tags"].ToString() : "";
var parent = !string.IsNullOrWhiteSpace(Context.Request.Query["parent"].ToString()) ? Convert.ToInt32(Context.Request.Query["parent"].ToString()) : 1088;
if (!examineManager.TryGetIndex(Constants.UmbracoIndexes.ExternalIndexName, out IIndex index))
{
throw new InvalidOperationException($"No index found by name{Constants.UmbracoIndexes.ExternalIndexName}");
}
var searcher = index.Searcher;
var criteria = searcher.CreateQuery(IndexTypes.Content);
var filter = criteria.ParentId(parent).AndNot(x => x.Field("umbracoNaviHide", 1.ToString()));
if (!string.IsNullOrWhiteSpace(tags))
{
filter.And().Field("tags", tags);
}
if (!string.IsNullOrWhiteSpace(searchQuery))
{
filter.And().ManagedQuery(searchQuery);
}
var res = filter.Execute();
}
