Hello Searched around, but could not find this mentioned.
I've noticed the following behaviour in 7.4.5: [explain analyse] select * from foo where col1 = 1 or col1 = 2 or col1 = 3 or col1 = 4 or col1 = 5 or col1 = 6 or col1 = 7 or col1 = 8; where an index on foo.col1 exists. The above works fine - the index is used. However, extend the where clause with an extra line (say, col1 = 9) and the index is no longer used. Is there a parameter I can SET to extend the number of items allowed for index usage? Any pointers would be appreciated.
