VCF Tools are the best place to start. I would perhaps double check that the expected filter criteria actually match the data in your file. The match really does have to be exact. If still stuck, please share an example line that you want to find, the attribute you think you are looking for, and the exact tool used along with parameters. We can help more to help tune the search/filter.
The tool "Filter" can be used just about like any text editor "find" function. It may take a few tries to discover the best keyword(s) to use for how your data is labeled.
If really feeling up to more, could also use "Select". The logic for the regular expressions is described on the page. There are endless examples online, and everyone has to give these a test (or twenty) for the more tedious searches. Still, an option if you wanted to try.
Hope one of these works out for you, Jen, Galaxy team
