How to get best help from community

Hi Support team,

I have been using community forums Q&A and support of gurus very grealty through it. The only downside is that when a support replies to a question and it is not either coorect or relevant or unnecessary, my whole topic will be out of the radar of others, examples are not limited to below:

https://community.powerbi.com/t5/Desktop/Using-Slicer-to-turn-on-and-off-a-filter/m-p/747238#M360182

How I can get the answers I needed correct and complete and avoid being unseen or asked irrelevant questions for more unnecessary explanation?!

Thanks
