Hello and thanks for your comment!
About the issues you are experiencing:
1) CSV: have you tried to increase the PHP maximum execution time?
2) Quick search by default use the AND operator but you can change it if you want (write a support request on the forum and we will explain how)
3) DaDaBIK 6 will also allow to use AND/OR operators for a field during a search, simply typing the operator in the textbox (e.g. "apple OR banana") :)
