Search not returning all results

I'm trying to get into Camilladsp but being new to both this app and Linux I'm having a few problems installing it correctly. Rather than try to read all 192 pages, I thought I'd search within that thread to find all references to the word 'install'. When I do that though, I get 10 pages of search results, the oldest of which links to page 72 in the thread. The word 'install' occurs multiple times in earlier pages - why are they not showing on the search results?

If there's a way round this limitation on search results, can you point me to it? If not, I can imagine that I and many others will be asking questions that have long since been answered, just because there's no way to find that answer. Could get very annoying to those who know what they're doing...
