Support for wildcards in formula parsing / evalution would be a nice contribution. POI's formula module is well designed and it should be possible to add support for wildcards without changing much code. Support for simple wildcards e.g. ”*apples*” is straightforward and should take a few days. You will need to re-visit formula implementations and make sure they understand the wildcard syntax. Support for complex wildcards like ”*”&A1&”*” is harder. It will require changes in the formula parser to support this syntax and then changes in the evaluation code. We may need to re-factor some core classes to suport it. A full-time developer familiar with the POI architecture should be able to complete this task in 7-10 days . The point is that POI is a volunteer project and people contribute in their free time, mostly off hours, by little bits.
