need to filter on many, many reqs.

I have a filter for req. number in my report in OBI.  I have 257 reqs. I need in the filter.  I put them in separated by a semi-colon.  It just hangs.  Tried with 100 reqs.  Still hangs.  How can I filter on these reqs. without having to run the report piecemeal?  Thanks.
