Do you understand the difference between creating one index for each column and creating one index on all columns ? It is worth the huge increase in filesize ? Is the slow-down on data entry (where entering one row must modify many indexes) worth the speed-up in your SELECTs ? Do you understand that any SELECT will use only one index ?
