I have multiple servers, web, index, and search. Do I have to configure the PDFiFilters on each server?
iFilters need only to be installed on the indexing server(s). However,you may have some additional desirable configuration required on otherservers, such as PDF icon, etc.
for pdf icon, you'll be required to make chanes in doclib.xml file, theinstructions r mentioned in spdminguide...
[SharePoint 2003]I recently found that PDF files could not be found on teamsites (WSS2).Teamsites search use the SQL server Full text search to find data.If you have a separate front end and database server, then you'll haveto install the PDF IFilter on the database server as well and do someextra configuration.
