That doesn't help. I know those resources exist and I check them in the hopes that I may stumble upon what I need.
For example, the combobox component provides a list of items to select from and filters them by starting to enter the name in the text filed. The issue was that it was only looking at the start of the text of the item and not whether or not it contained the entered text. I knew from other components that I could select a filtering type but when I checked the Guide - Under Filtering, there was no mention of a filtering propery. https://blazor.syncfusion.com/documentation/combobox/filtering/
Okay, I checked the demo pages next - no joy.
I then tried the API Reference looked for about 45 mins - no joy. Finally, I did a search for filter in classes and there was a filtertype associated with the Dropdowns but I still didn't know what property I should use on the combobox component or if it was applicable.
Finally, I did an overall search, which returned 915 results, I started to review and found Filtering Property for AutoComplete so I just tried it on the Combobox and it worked. There is another issue inconsistency. On one component the property name may be different from another component but do the same thing e.g. filtering.
The point of all of this is it took me around 2.5 hours to find this information which should have taken about 10 minutes if there was a component / property matrix as a part of the documentation.
