Hi devs 
I last week added the category filter to the module and it is working well, you can test it out and suggest what you think about it for what we so-far have on it, you may check it out from the module’s github repository.
Another thing is that this week am implementing search syntax and i need more feedback at Chartsearch Module -- search box behavior / syntax than ever, i have just added some comment there and please check it out and reply towards my comment, or else add your comments at the ticket for this task at https://issues.openmrs.org/browse/CSM-25.
