With RStudio Version 1.2.1335, Build 1379 (f1ac3452), under Windows 10, in a fresh session, and using R 3.6.0 I find that help.search(), e.g., help.search("log") produces empty results even though the same command produces many hits when entered in the R GUI. As well, this command works fine in RStudio with R 3.5.3.

Same problem here on Manjaro Linux. After upgrading to R 3.6.0 and RStudio 1.2.1335, e.g. help.search("log") does not return any results anymore. A stand-alone R console indeed does work, as does the "Search Engine & Keywords" under the RStudio Help tab. Session info:
