active report - dynamic search by user

[ddma]

I would like to add posibility for a user to use dynamic search.

For example, a cell "file name", in which user could write i.e. "file1" and get all the values with "file1" from column.

1. Is there a way to do it without data drop-down lists? I would like to avoid solution where user looks into 100-200 values to find needed one.
1. Is there a way to do it without "prompt" functionality? For example I dont want to have additional page for prompts. But if in executed report user will have empty text label "enter filename here" and user could fill in text label and query will be ran based on entered label value in report - that should work.
2. Is there a way to do it as multiple-time action? So user could do multiple searches. Search->Reset Filter (button?)->Search Again
