Jonathan, thank you!
It does work without the parentheses.
I would suspect an encoding problem, but for that the problem only manifests in the OPAC, and not the intranet.
I came across this issue while testing after migrating from MariaDB to Percona MySQL. Your reply prompted me to check the encoding of the new database, and it's unfortunately Latin-1. Since these are parentheses and not diacritics, I’m not sure what my expectations should be, but changing to UTF-8 is a place to start. Httpd.conf does have UTF-8 set as the default.
FWIW, my source records were encoded in MARC-8. I used MarcEdit to convert them to UTF-8, and it appears that Koha automatically converts anyway on import. When I loaded these records into Koha, I used bulkmarcimport.pl on the command line.
I'll ask that the default character set of the database be changed, and see if that helps. Thanks again. I'm embarrassed that I didn't think to omit the parentheses, or rather was belligerently insisting to myself that they should not have been a problem,

Hello Tasha,
I've created 2 records with
245$a Electroactive polymer (EAP) actuators as artificial muscles and the following query returns the 2 results.
/opac-search.pl?idx=&q=Electroactive%20polymer%20%28EAP%29%20actuators&weight_search=1
Tried on master and 20.11.06.
Maybe a silly idea: does it work without the parenthesis?
Could you try and recreate it on a sandbox
(https://wiki.koha-community.org/wiki/Sandboxes) and provide us a step by step plan to reproduce the problem?
Regards,
Jonathan

Also, the Koha manual indicates the following, which suggests to me that I ought to get hits on the unquoted string:

My expectation for this particular case is that all of the above methods would yield results. If there are any pointers to be had, I thank you if might point me to them so that I may be better poised to help users.
