Mysql : Match Against query -

-

due bigdata want use match against in place of like. column full indexed. alternate of query, in match against.

mysql query is:

 select count(*) keywords sb_keyword 'a%'

is query is?

select count(*) keywords sb_keyword 'a%'

that should benefit index(sb_keyword). fulltext index not practical query, either stands or using where match(sb_keyword) against(+a* in boolean mode).

it take time walk through values starting count them. index suggested helps because , index (usually) smaller entire dataset due having fewer 'columns'.
