Hi, Bao Toan Nguyen, Thanks for your interest in FastBit software.
Based on what you have said, it is likely that your queries can be answered with indexes built by FastBit, however, the data records you want to retrieve are actually scatter around in the data files. Effectively, FastBit has to read the whole data file and then pick out the entries you want. A strategy to improve the retrieval speed is to reorganize the data records so that you don't have read the whole data file. Hope this helps. John On 1/4/12 7:04 PM, bao toan nguyen wrote: > hi ! K.
