Re: Large database

I have added multi row indexes to some of the fields, that increased the speed of view records. But problem remains there for our summary pages(showing some trends, some top values and counts) which contains several queries like,

count(event_id) from xyz where field='value' group by field;
select count(event_id) as c, field, field2,f ield3 from xyz group by count limit 10;
etc

I dont know how can i apply indexing affectively for the queries that includes count. Any idea?
