Dear reader,
I'm trying to use solr for a hierarchical search:
metadata from the higher-levelled elements is copied to the lower ones,
and each element has the complete ocr text which it belongs to.
At volume level, of course, we will have the complete ocr text in one
and we need to store it for
ch happier (speed of some
> operations). Might be something to test if all else fails.
Ok...
Thanks,
J. Barth

Dear Shawn,
see attachment for my first "brute force" no-compression attempt.
Kind regards,

or by per-field basis?
Here's the issue that added the compression to Lucene:
https://issues.apache.org/
buted on disk and more I/O is necessary to
retrieve the fields (usually this is a concern when storing large
fields, like the entire contents of a document)."
But in my case (with docValues=true) there should be no reason to
access *.fdt.
Kind regards,

Zitat von Jo
I'll found out that "storing" Documents as separate docs+id does not
help either.
You must have an completely separate collection/core to get things work fast.
Kind regards,

ecause of direct match (and not via {!graph... ) ?
The only way to do so seems a {!boost before {!graph, but what I can do
there is not dependent on the match nor {!graph, I think.

Dear reader, I've found an different solution for my problem
and don't need a depth dependent score anymore.
Kind regards, Jochen

Dear reader,
why does +(-x_ss:y) finds 0 docs,
while -(+x_ss:y) finds many docs?
Ok... +(*:* -x_ss:y) works, too, but I'm a bit surprised.
Kind regards, J. Barth

ies possible?
I've got some complex queries with a "kernel" somewhat below the top
level...
Is "canonical" json important to match query cache entry?
Would it help to serialize this queries to standard syntax and then use
filter(...)?
Kind regards,
Jochen

so the + before the »filter(« shouldnt be strictly necessary nor be the
problem,
and the + efore class_s:meta isn't necessary, too, but can't be the
problem, too, in my opinion.
What I found out is, that, "+" and "-" have higher precedence than "AND"
and "OR"... but I don't see my error...
Does someone has a hint for me?
Kind regards,
Jochen
