Usage example with a context:
If you try to make a field that already has data an indexed field with no duplicates and the data does not consist of unique values, the system will not let you save the new index.
First of all, let me make sure that I semantically get this right. What this says, as I understand it, is that there's a field that has data and the data have been indexed, i.e. the field has an index. Is that correct? If so, is it alright to say something like this:
These days, I'm having my computer the only way to reach to people because I'm under house arrest. I can't go outside.
I know, this example probably sounds like an awkward way to say it, but that's all I can come up with at the moment. Again, the point for me here is to make sure that I have a coherent understanding of it.
Is this a common pattern in English? Could you please give me some more examples of how to use this pattern?
