Using expressions in sort and json stats

2023-11-01 Thread Ing. Andrea Vettori
Hello, I’m looking for the most efficient way to specify sorting on expressions when they’re complex. For example, suppose that there are fields a1, a2, ….., an and I need to sort for the sum of them. In this case it’s “easy” using sum(def(a1,0),def(a2,0),…,def(an,0)) as expression. Now suppose

I suspect this is an XY problem, can you elaborate better what's the original task to be solved? It's unusual to use those sort expressions in Solr. Maybe we can solve it differently, at indexing time or maybe using some ranking models (like a linear one on learning to rank, but using not learned

Indexed Content Lost on Restart

I'm running a single instance of Solr 9.4.0. I've noticed that when the solr service is restarted, or when the server is rebooted and the service starts, the indexed content seems to disappear from my solr cores and needs to be re-indexed. This wasn't happening when running Solr 8.x, and I'm not su

I'm unsure. I queue the content for indexing and rebuild the indexes using the Drupal "Search API Solr" module. It does appear that the module is aware of concept, though: https://www.drupal.org/node/2009804#server-index-status -Original Message- From: matthew sporleder Sent: Wednesda

OK, I figured this out. When I created the cores, I incorrectly set the dataDir property values. That put a bad dataDir value in the core.properties file associated with each core, and so each time the server started it looked for data in the wrong place. Removing the incorrect value and re-inde

Sorry, it took too long to get back to this one. The search query "http://host:8983/solr/v9/select?&q=*&rows=10"; consistently took ~500 ms. With "distrib=false" all the 96 shards have QTime 0-25 ms. Does this mean aggregation of results from all the shards is taking ~475 ms? I also tried shards

edge n gram tokenizer could be useful . that would shift query time compute to index time at the cost of bigger index size. Sent from my iPhone > On Nov 1, 2023, at 7:02 PM, rajani m wrote: > > Sorry, it took too long to get back to this one. > > The search query "http://host:8983/solr/v9/s
