Haven't tested but reading the code it looks good to me. Think you can go ahead and merge. Awesome contribution :)

I can't see relationships option when I am in advanced query. Can someone help me with this?

Hey @krishnapraveen7 ,

Unfortunately this feature has never been released due to a lack of time to maintain the project. I'll try and create a tarball if you want to give it a try, but I won't be able to create an official release anytime soon (would require more tests).

[krishnapraveen7]

Thank you @stellasia. I would really appreciate if I can get a tarball.

[stellasia]

Can't attach the tarball here, format is not supported...

I have uploaded here for now: https://drive.google.com/file/d/1GOoY97XfjsrCDKfuEA3t3CZoSRHuvDgW/view?usp=sharing

Be aware this is a development version, not well tested, so some bugs and regressions are possible, but the relationship feature is there.
