[Ramnik Bansal]

Getting following error in using help.search

>utils::help.search("linear models")
Error in help(db[i, "topic"], package = db[i, "Package"], lib.loc = lib,  :
  'topic' should be a name, length-one character vector or reserved word


> example(help.search)

hlp.sr> help.search("linear models")    # In case you forgot how to fit
linear
Error in help(db[i, "topic"], package = db[i, "Package"], lib.loc = lib,  :
  'topic' should be a name, length-one character vector or reserved word


How to sort this?
