There are several sites in the hundreds of thousands of pages. As for practical limits, it depends a lot on how many pages you plan on indexing. Some operating systems limit files to 2 GB in size, which can become a problem with a large database. There are also slightly different limits to each of the programs.

Right now htmerge performs a sort on the words indexed. Most sort programs use a fair amount of RAM and temporary disk space as they assemble the sorted list.

The htdig anc stores a fair amount of information about the URLs it visits, in part to only index a page once. This takes a fair amount of RAM. With cheap RAM, it never hurts to throw more memory at indexing larger sites. In a pinch, swap will work, but it obviously really slows things down.

Additionally it is no longer reliable at extracting data. SourceForge is a new service for open source software. You can host your project on SourceForge servers and use many of their services like bug-tracking and the like. Before you go anywhere else, think of other ways of phrasing your question.

Most annoyingly, it puts the onus on an individual to answer, even if that individual is not the best or most qualified person to answer. This is not a one-man show.
