I just did a search of the BI here and it took about 2 seconds.
I'm not sure what the issue is in your case. Is searching always that slow? even on other titles? Are single word searches slow also? Is it only slow when you are searching for phrases in quotes?
Depending on how many titles are installed, searching all titles of one group should not take more than 10 or 15 seconds. Usually it is much quicker.

But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness. (Rom 4:5 AV)
