Here's a sampling of what might be some of the better ones:
index design -,558435 (Backup and trimming data idea)
*, index, InnoDB -,530328 (Does LIMIT 1 without ORDER BY ID bring the record with minimum ID?)
2-field index -,519675 (problem for selecting range of date between 2 dates)
index -,519897 (Creating an Index)
EXPLAIN, index, RoT -,519097 (Help optimizing query/index)
covering index -,514321 (Strange performance with JOIN/COUNT)
index-10-30 -,508243 (MySQL 5.1.49 - Optimal settings for memory usage)
index -,508224 (indexing)
*, INDEX, not using index -,507723 (Problem with a query performance)
bulk, char vs int, index -,505513 (Best primary key or index)

compound index, key_len -,452643 (Multi-Column indexes)

index -,418955 (Stop using filesort)
index join -,411522 (ideal indexing for inner join, rowcount of 1)
index -,409094 (Table marked as crashed and last (automatic?) repair failed)
index, subquery -,409897 (Partition on day of year)
index design -,409053 (MySQL not using indexes)
