Why are you trying to do this? I'm wondering if this is an XY problem. For instance, you could use a multivalued field of _text_ type with a positinIncrementGap of 100. Now you simply search (don't need function queries) for "Deli NCR"~90 and you wouldn't match across multiple entries. There are other tricks on this technique if, for instance, you didn't want to match "Deli NCR India"
So if all you're doing it matching this is a much more robust solution. But without some statement of the problem you're trying to solve, i.e. the use-case, it's hard to suggest alternatives. Otherwise you're stuck with custom code I'm afraid.
