How to fix warning in wordforms.txt during sphinx index?

Question

I am new to sphinx. When I am rotate/start the index, it shows.

 WARNINGS:invalid mapping(must be exactly 1 destination keyword)(wordforms='Sufenta'>
 'Sufentanil Citrate Injection'). Fix your wordforms file 'usr/local/sphinx/var/data/wordforms.txt'.

But after rotating, it gives and then it shows Rotated successfully message also. Functionality is ok. But I dont know, why every time it shows warning in wordform.txt file

Answer 1

As the warning says, you have a 'wordform' with multiple words on the 'destiniation' side.

Don't do that.

Fix your wordforms file.
