If the name Melida were in this database, then when you are reading the name in her post, (or in this one)the name Melida would be underlined. Then you can click on Melida and get to the meaning. But it's not underlined here, because it's not in the database.
So probably Melida--is one step ahead of you--checked the database, couldn't find her name, and came here to the board for further investigation.
Hope this helps clear your confusion.
