Please advise how I can improve performance of query searching for telephone
numbers. I have a table with over a million records of phone numbers in a
single indexed field. To find one phone number takes nearly 20 seconds.
Aside from hardware upgrades, how can I improve the performance of this
query? Thank you in advance.
