Actually, 1M records isn't all that much for a Solr index, so I'd simply test with the copyfield alternative as it's much easier.
About compression: this simply compresses the *stored* data, which has essentially no effect on index search speed, but will affect the size of the file (*.fdt) that contains stored data. Here's a good reference: http://lucene.apache.org/java/3_0_2/fileformats.html#file-names The fields you copy *to* should probably not be stored (stored="false"). The idea (I thought there was a Solr patch for a new Filter, but I can't find it) is to have something similar to the SynonymAnalyzer in Lucene In Action that inserts the special token at, say, the end of the term *as well as* sending the original term. Say you're indexing "running". Your index process would put in "run" and "running#". Now when searching, when you want exact match, you search for the terms with the '#' at the end. Yes, it makes your index larger, but whatever you do will make the index larger.
