Lucene "contains" search on subset of index

I have an index with around 5 million documents that I am trying to do a "contains" search on. I know how to accomplish this and I have explained the performance cost to the customer, but that is what they want. As expected doing a "contains" search on the entire index is very slow, but sometimes I only want to search a very small subset of the index (say 100 documents or so). I've done this by adding a Filter to the search that should limit the results correctly. However I find that this search and the entire index search perform almost exactly the same. Is there something I'm missing here? It feels like this search is also searching the entire index.

Adding a filter to the search will not limit the scope of the index.

You need to be more clear about what you need from your search, but I don't believe what you want is possible.

Is the subset of documents always the same? If so, maybe you can get clever with multiple indices. (e.g. search the smaller index and if there aren't enough hits, then search the larger index).
