Global Search on website using multiple table models

I have been trying to implement global search for my website. I found solution for website search for single table model. But not with multiple table models having similar kind of fields.

Please suggest possible solutions. Is it possible to solve with Elasticsearch or spinix search extensions of yii2.

If yes then provide any example to do.

Thank you

Yes. It’s better to search with either Elastic or Sphinx. Both are building index from whatever you want.
