Searching for a note with "R&D" in it returns nothing

[marcxm]

As in the title. I assume it has something to do with the way Whoosh processes it, but none of the ways I know to escape ampersand worked. What I've tried:

"R&D"
'R&D'
R&D
R D
R*D

Hi @marcxm. The trouble here is that R&D will get "tokenised" into ["R", "D"] with the ampersand thrown away as irrelevant. Then, these tokens are also filtered out as they are single characters.

There are likely some tweaks that can be done here but experience in other capacities has taught me to tread carefully with full text indexing logic, so this may have to wait until I have some time to consider a solution and the implications it would come with.
