I have an index with 2,5 million documents. A document is formed in this way: - 15 fields index - 1 field stored but not indexed, whose value is one string of 500 byte. A search in average gives back the 3000 document. As 3000 id of documents is given back a lot fastly, the 3000 documents instead demands at least 20sec. for being given back!!! I have tried with a string of 5 byte instead that of 500, and the 3000 documents are given back in only 1sec! The question seems had to the size of the file .fdt How I can make in order to reduce the time in the first case?
