<p>Thanks for the pointer, maybe a check against a fixed vocabulary
can be enough.<br>
</p>
<p>This also mean reindex all the archive. Is it possible to reindex
only title and keywords? Full text can be a problem to reindex if
you've a lot of pdf, for example.<br>

<p>Hi!</p>
<p> I've found that the virus can be referred also as "SARS
COV-2" so maybe you can add also this. But beware that Eprints

This also works with "title" as you would expect.

can be "covid-19" OR "coronavirus" as well as including
some allowance for adding an:</div>

<div> "OR title LIKE '%covid-19%' OR title LIKE
'coronavirus' in MYSQL-speak.</div>
<div><br>
</div>
<div>Am I able to do this using the EPrints::Search plugin?
I've tried reading the codumentation and experimenting
with it, but I'm not getting very far.</div>

<div>If it's not possible I can think of a number of bodges
for it, but decided it was best to attempt the proper way
