I have done what Andy have mentioned and it seems to work for me.

1. Its a custom text field
2. Search weight is at 3
3. This text field contains only one word for test: webhostingcube

Now I tried to search with the word, however it didnt worked for first 4-5 times, however after doing reindexing again it started working just fine.

Hope this helps.
