Searching on multiple index files is incredible fast. We have 10 different index folders with different sizes. All folders together have a size of 7 GB. Results come back usual within less than 50 ms. Getting results out of the index i.e. reading documents is expensive and you will have to spent time here to get a good performance. You will need to look into - Topdocs - Extracting results in an ordered way, i.e. sort by index and within an index by document id. This will help to minimize disk head jumps and gave me a tremendous boost. - Extracting only what you need (using a special read filter I do not recall the name right now and I do not have access to my sources at the moment of writing this)
