After a few months of release, our site is currently up to approximately 11,000 web pages and continues to grow rapidly. One disadvantage is that we don't have dynamic string-based search implemented, yet, so finding content can only be achieved through highly structured web directory-like cataloging on the site. For now, it works. However, we know that search needs to be addressed within the next year or so.
We've started looking into solutions like Lucene but we're not sure of what the best solutions are for search. Would any of you be able to suggest options?
