I have been searching for MONTHS for a good intranet file search engine, and I am happy to report that yours is the best I have found after testing out many similar products and online services.
I have deployed your cloud-based solution on Amazon Web Services and thanks to you I am offering my client a multi-server full text index/file search service across multiple websites from one simple search form on their intranet. We are protecting some files using simple htaccess, and Searchdaimon crawled those protected files just fine. I also got it to log in and crawl our WordPress intranet site just fine as well but I am mostly using it to index protected and unprotected file directories in several locations. Nothing else I have found does the job we needed of indexing all the text inside protected documents. Your solution works for us, and I think it is simply the best one out there right now.
Nice job, Searchdaimon!
