In short, proxycache cannot do that. We designed a totally different,

Moreover, note that negative caching could be an issue if resulting from
a search that returned nothing because performed with insufficient
privileges: subsequent operations with adequate privileges would get
nothing if the negative response were cached...
but if I do a search
"(uid=bar)" and there is no entry with that uid, this "negative"
result is not cached, and every time I try that search, slapd
translates the search to the external ldap server. Is it somehow
possible to configure slapd proxycache to cache searches with no
results so slapd returns the client the answer instead asking external
ldap server everytime?
Not true, we added negative caching to proxycache in 2.3. See the
slapo-pcache(5) manpage for the relevant configuration keywords.
