Solr
Apache Solr is a search platform built on Apache Lucene.
I have official Solr 8.0.0 running in a Docker container. I am learning how to put data into it now.
Docs
I've been watching this guy's videos. https://factorpad.com/tech/solr/tutorial/solr-tutorial.html He says the standard Solr tutorials jump in too fast and I tend to agree but these are a bit too far the other direction. But I am sticking with it.
Solr Reference Guide; includes getting started instructions.
How are docker volumes used?
I am keeping solr's data in a volume that can be found at /home/docker/volumes/solr_data/_data on Bellman. It's mounted at /var/lib/solr in the container.
Where's the web server?
I have it running behind my firewall right now at https://solr.wildsong.biz/.
How to do stuff
Get shell access?
To get a bash shell,
docker exec -it --user=solr solr bash
"Cores" are the setups containing data and configuration. This worked to create the "taxlots" core.
docker exec -it --user=solr solr bin/solr create_core -c taxlots
Create a core?
The following is assuming the core name is "films" and we're using the sample data that came with Solr download.
cd source/solr/solr-8.0.0
Create the core
bin/solr create_core -c films
Edit the schema per the tutorial. First using the GUI, add a field called "name" set type to "text_general" and uncheck "indexed" and "uninvertible". Then to demo using the REST command, we did this; I am not sure what it does. But we did it.
curl -X POST -H 'Content-type:application/json' --data-binary '{"add-copy-field" : {"source":"*","dest":"_text_"}}' \
http://localhost:8983/solr/films/schema
Add data to it
bin/post -c films example/films/films.json
If you run the same post command twice it will just index the same data again, so it changes nothing internally.
Show the fields in a core's schema
Wiki bug?? If I put the http in the right place on the next line I cannot save it. You know what to do.
curl ://localhost:8983/solr/films/schema/fields
