Try to EXPLAIN the query and verify that the index is actually used.
There are a lot of reasons why this query would probably NOT be using
the index.

Subject: [sqlite] Inner Join Performance Issue

Hello Forum,
[>> ] 
I have a select that joins 15 Tables the where clause consist of 8 like
relations (all fields are indexed), this is to implement a sort of
"search
engine".
The performance is awful. It takes around 10sec. 
Is this how it should be or is there anything I can do?

If you need more infos pls. let me know

Thx
Ralf
