### 2/5 — Global search not working, please fix it

*2020-02-07*

"Search in all" feature is not working , if you do not use the exact word in the dictionary, the dictionary is not suggesting it at all.
Example : look for "asteroid". It will not come up
If you search in the astronomy dictionary it will suggest "asteroids" even if you didn’t use the plural
