|Subject||Re: [greenstone-users] why searching on multi collection is too slower?|
When you search more than one collection at a time Greenstone must search each collection individually, then merge the results. So the search time will be at least the sum of searching each collection individually.
50 seconds is a long time though... how big are your two collections?
Hi:I have two larger collection . so make supercollection col1 col2 config enable. But,whem I test the supercollection on the col1 and col2, it shows search time about 50 seconds, and same number hints on one collection is less than 10 seconds, why? regards.wangyu
