I have a table with 1,500,000 name and first name
I use Full text search on  name   and first name
when I use a contains expression like
select ... from table1 where contains( name,'abc')  the query take  45 secs
immediatly after this test I search for the same or another name and the
query take under 1 secs ....  

an hour later app.. I run the same test and the first query take 45 secs again

I try a test with search 1,000,000 different name ( for validate if the
problem was the caching ).... the first on take 45 secs app and the 999,999
others case take under 1 secs  

on my local computer    all search run under 1 secs

Peter Yang from microsoft private news groups  think that is  a memory
(cache) problem... !!! but I think  45 secs is too high for a single unique
key search in link with a cache problem

could you help me ?
