I would like to point out an (obvious?) alternative way to create
search engine. Simply use htdig <http://www.htdig.org> by specifying
following in the Doxygen config file:
SEARCHENGINE = YES
CGI_NAME = htsearch
CGI_URL = http://localhost/cgi-bin
DOC_URL = http://localhost
"htsearch" is the CGI executable that comes with htdig.
After using htdig for a few days, I found it very very useful.
I highly recommend it.
I was not able to use "doxytag -s search.idx" because it is such a
memory hog that it would have taken many hours on my Linux box with
512Mbyte of RAM due to constant paging.
I know that doxytag takes about 15 minutes on directory with about
30MBytes of HTML files. However, 200MBytes of HTML is too much for
doxytag to handle.
