Hi there,

I'm wondering if using an IdsFilter will get me real (!near) real time
results as in real time get?

Cheers,
Hans

IIRC, a Get request will query both the Lucene index and the transaction
log (real-time), while any search will only access the Lucene index (near
real time).

Hey

correct. Whenever you are doing a search, you are always relying on lucene
search capabilities (even in case you are doing a simple id filter), which
means a refresh has to happen, before the data you indexed is available for
search. A search does not query the transaction log (because it is a simple
journal and not an inverted index suitable for search), where as a GET
(which simply uses the id) can check in the transaction log.

I am currently trying to sum up a little bit, what happens under the hood,
how the transaction log is used to provide real time get (how the
transaction log is used for recovery on startup), etc... hopefully I can
make a real blog post from that.
