Searching for one item exactly from Portal

Question

If I need one thing from Portal is there a way to search for it explicitly - at the moment the search result brings back a multitude of things that sound like the item I am searching for (happens to be a layer file) and also includes the actual thing I am looking for. Ideally I want either 0 or 1 item returns so I know either that search result returned successfully or not. This is the code I'm using where I am hoping that the "search" should work in the way that I explained above: public static async Task<List<AgolLayer>> GetAgolLayersAsync(int numberOfResults, string search = "") { var portal = ArcGISPortalManager.Current.GetActivePortal(); List<AgolLayer> agolLayers = new List<AgolLayer>(); if (portal.IsSignedOn()) { var query = PortalQueryParameters.CreateForItemsOfTypes(new List<PortalItemType>() { PortalItemType.Layer }, "", Module1.GroupID, search); query.Limit = numberOfResults; //Loop until done var portalItems = new List<PortalItem>(); while (query != null) { //run the search PortalQueryResultSet<PortalItem> results = await portal.SearchForContentAsync(query); portalItems.AddRange(results.Results); query = results.NextQueryParameters; } foreach (dynamic item in portalItems) { AgolLayer agolLayer = new AgolLayer(item); if (agolLayer.IsValidLayer) { agolLayers.Add(agolLayer); } } } else { Debug.WriteLine("User not signed in - so layers cannot be retrieved."); } return agolLayers; }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I have found that if I search for a layer file and include the .lyrx suffix to the search string parameter it brings back 1 result. Which is fine - but I have put a constraint to bring back "Layer Files" only. So this kind of makes the constraint for "Layer Files" superfluous.

I'm not happy with the search algorithm here.

This is a bit rubbish - I can't believe this is the only solution.

Exactly the same issue using the python api, the typical solution will be to iterate the results and find one that matches name/title/type exactly. Again if 2 items have the exact same name/title/type they will still both be returned.
