I think that is a leftover from 2.2, and the sense of incremental there
was that when squatter runs reindexes the entire content, rather than
reusing what it can from the existing index. So incremental referred to
a batch, rather than real-time, update.
Apparently 2.3 does have a batch incremental mode. That sounds like a
Also, does anyone know what this means for searches on material that has
changed since the last squatter run? I have assumed, and hope, that the
search procedure is something like this:
search in the squatter index
remove results referring to deleted items
do an unindexed search on items added since last index.
Is that right? Or, for example, are new messages just ignored?
