In the Web version, when I go into ADVANCED search, I have no option to actually search anything, only to set up my search and then to save it as a filter. I don't often want to save a filter, but rather just want to conduct a one-time advanced search on particular fields. Can you fix?

Also, there is no field in advanced search for free text, only for specific fields and their options. I occasionally want to search some keywords that I know will be in the description or title field, along with optional other conditions
