[deleted] hey regarding the same I've contacted @clarkwinkelmann via email.
If you are interested we can request him for related post extension after v1.0 release.

Related post extension
once go through the plugin page and attached imgur pic regarding related post extension to understand about the requirement.
i am looking for all the features which are mentioned in wordpress plugin page
---- his email reply ----
For the "related discussions" with manual selection and default discussions from the same tag if none are set, probably around 2-3 hours work.
If we wanted to add automatic "relevance", we would need to choose an algorithm, and I have never implemented that kind of thing before. Since the Flarum search is already slow, I would imagine an automated query for related discussions would also have poor performance, unless we put it inside of a CRON job or async job. If we do that we will probably reach 4-5 hours as in my original estimate.
The cheapest option with me is definitely open-source since I offer a lower rate for it (50CHF/h, around 53USD at the moment).

Let's stick to basic level 3hours of work . I'm ready to sponsor for 1hr (53 USD) if you are ready we need to find 1 other sponser. 53x3 = 159 USD
Maybe @ctml @[deleted] are also interested in this I'm not sure . But sure we can find 1 other sponser it's the most requested extension.
After the initial release of related discussions extension we can plan for a upgrade.
