So you've got a MultiReader over some number of indexes, and in order to delete stuff matched with that MultiReader you need an IndexWriter for the specific index that holds the selected term. In Lucene 4.0. Is that right?
There are getSequentialSubReaders() and readerIndex(int docID) methods in the MultiReader hierarchy, and a directory() method in DirectoryReader, but that's pretty convoluted and readerIndex is protected so it may not work anyway. There's probably an easier way but I can't see it. Could you just loop round the indexes individually, opening a single reader on them one at a time? -- Ian.
