I cannot search Pronominal (you, me, they, he etc.)

I’am creating my own dictionary using Discourse.

When I search almost of the words (watch, see, eat, play etc.) using Search mark :mag_right: within my website, these words can be shown successfully.
However,when I search pronominal (for example, you, me, they, he, she etc.), there’s no search result (but these words exist). I don’t know what’s wrong.

If someone know how to fix it, please tell me.

Thank you!

There is a topic on this already, it has to do with how postgres indexes search terms.
