Partial search on object with multiple values

Hi all,

Please help me on the requirement...

I need to create a query filter in which user wants to search with multiple objects and with partial data for ex:- i have data like

1. This report belongs to Australia.

2. Happy christmas

3. Have a lovely day

4.Good evening chennai

5. American express

Like this  i may contain vast data,here user needs to search in the prompt as "Hap,repo. Then we need to get output as

1.Thia report belongs to Australia

2.Happy Christmas

Is this search is possible in BO or any other process to acheive the same.

Thanks,

Madhavi.G
