I'm trying to use the tiki-wiki software. It has several indexes
which store the web page's data as an index criteria. The problem
comes up when a web page is a large web page. It can't store the page
in the index.
Do you know of another way of dealing with this issue aside from
re-compiling or recoding the indexes?
