I understand that lucene's AND (&&), OR (||) and NOT (!) operators are
shorthands for REQUIRED, OPTIONAL and EXCLUDE respectively, which is why
one can't treat them as boolean operators (adhering to boolean algebra).
I have been trying to construct a simple OR expression, as follows
q = +(field1:
One of my previous mails to the group helped me simulate short-circuiting
OR behavior using (thanks to yonik)
_val_:"def(query(cond1,cond2,..))"
where if cond1 is true the query returns without executing the subsequent
conditions.
While it works successfully for single attribute, I am trying to
Does the order of fields matter in a lucene query?
For instance,
q = A && B && C
Lets say A appears in a million documents, B in 1, C in 1000.
while the results would be identical irrespective of the order in which you
AND
A, B and C, will the response times of the following queries differ
Hi,
I know that SolrCloud allows you to have multiple shards on different
machines (or a single machine). But it requires a zookeeper installation
for doing things like leader election, leader availability, etc
While SolrCloud may be the ideal solution for my usecase eventually, I'd
like to know

ey - Could you elaborate more about the "broker" core and
delegating the requests to other cores?

the RAM and less than 10% is available for OS caching ( since replica takes
another 40%). Why does unallocated RAM help? How does it impact performance
under load?
