getting 4 consective values in a query... this is interesting and hard

[ernestopogi]

I have a table
"search_log "
that logs all search by client
here are some of the fields query_date , query_result, query_code

here is the thing as the owner of the site I want to be able to see a user that searched four times in a row that has no result to be able to save them and stop the from being disappointed

if a client searches and there is no result it automatically inserts a data like this
query_date = NOW(),
query_result = 0,
query_code = LIKE '%querystring%'


now i want to be able to find a client that has four "CONSECUTIV E" searches in a row that has four zero "0" query_result


i am looking for something like this


query_date = 10/11/2001
query_result = 0

query_date = 10/11/2001
query_result = 0

query_date = 10/11/2001
query_result = 0

query_date = 10/11/2001
query_result = 0

they have to be consecutive

by the way my table is having 3 million records so Can you please advice me a query that can run faster

The Query should be like this

SELECT * FROM choosentable where query_result = 0 ORDER BY DATE Limit 0,4
