I tried to reproduce your use case by creating some sample data (with a few
millions of entries), but both the query plan and the performance were
similar in 9.2.4 and the current 9.3.3 beta version.
And I am still trying to understand your example query. Is it correct that

Hi,
Here is my issue.
I create a new container with Basex 9.3.2
I add a volume ContentDBs under my basex directory
ContentDBs has 2 directories and 1 files
I run this code from an xqm:
let $src-dir-items := file:list('ContentDBs')
let $debug := file:append('debug-a.xml', 'count: ' ||
Hi,
I am observing a performance loss between BaseX versions 9.2.4 (which I was
using so far) and 9.3.2 (to which I updated recently) when executing an xQuery
like this:

(: Open 2 databases and get all s :)
let $recsFromDb1 := db:open('db1')/record
let $recsFromDb2 :=
Ahh, good old MAB2 :-) ... but it was as complex as Marc21.
Thank you again for your tests and information. I will test that again with my
setup and let you know if I see any differences between your query and my query
and what could lead to the performance loss.
But probably I will not be
Hi Christian,
thank you for your answers. As you can guess the queries I sent in my original
email are just simplified examples.
The real XML structure is like the following (its library data in format
"MarcXML", here you see an example:
And I’m always delighted to be confronted with library use case. BaseX grew
up with library data; at that time, mostly XML variants of MAB2.
I made another intent to reproduce your setting by creating two databases
with MARCXML data (rather small, 10.000 and 10 documents each). This is the

Is there some way to iterate full-text matches to mark up in the node every

I have a use case where I have a long list of phrases which may appear in
the content set; if they do appear in the content set, these should be
marked.

Thanks, Michael, for the valuable observation. It might be that another
newly integrated optimization proves to be detrimental to your existing
query. I’ll try to find the culprit.
Just a minor question: In db2, a single document seems to be stored. Does
this mean that only one record is assigned
11 matches
