* Why indexer fails with the message like
	indexer: can't load library 'libmysqlclient.so.6' ?

    You probably didn't have MySQL libraries properly installed. 
    Just find out where is your libmysqlclient.so.6 is and put 
    the path to that file to /etc/ld.so.conf (Linux). 
    Then run ldconfig as root. 
    You can as well set up the value of environment variable LD_LIBRARY_PATH
    with the path to required dynamic libraries. This work on all OS.

* What is the maximum size of server(s) UdmSearch can run with?

    I don't know. I have  40 indexed servers with about 22000 
    different documents  and 140Mb total size. UdmSearch works fine.
    Everything is found in 1-2 seconds. The size of database with
    all indices is 130 Mb. People report that UdmSearch work fine
    with 600000 indexed URLs. You can check your SQL server manual
    for details on maximum database size and how to make it
    as fast as possible.

* I want to use UdmSearch for multiple virtual domains on a single box. 
         What settings do I need to change for that? 

    UdmSearch does support virtual domains. 
    No special settings are required.


* Is it possible to use different templates for searches, 
i.e. view search results in the design of different sites?

   search.cgi opens template with the same name. So, you
   can use the same search.cgi with different templates
   without having to recompile it. Just make one or several 
   hard or symbolic links for search.cgi or copy it under
   different names. search.cgi will open  template with the 
   name search.htm, search1.cgi will open search1.htm and so on.

   search.cgi also supports Apache internal redirect. You may 
   add these lines in Apache srm.conf :

AddType text/html .zhtml
AddHandler zhtml .zhtml
Action zhtml /cgi-bin/search.cgi

   Then put search.cgi in your /cgi-bin/ directory and put HTML template 
   anythere in your site directory structire under name search.zhtml. 
   Now you may open search page:  
       http://www.site.com/path/to/search.zhtml
