Configuration SOLR
sudo mkdir -p /var/solr/data/tethys_data/conf
sudo mkdir -p /var/solr/data/tethys_data/data
Configure Stopwords for your solr index
Solr has the ability to read in a list of stop words, or words that should be ignored during indexing, so that those words do not clutter your index and are removed from influencing result relevancy. Add a list of common stop words to your stopwords.txt file.
sudo nano /var/solr/data/tethys_data/conf/stopwords.txt
So your file might look something like this:
#Stopwords for example.com
a
an
and
are
as
at
be
but
by
for
if
...
Configure Synonyms for your solr index
sudo nano /var/solr/data/tethys_data/conf/synonyms.txt
# Synonym mappings can be used for spelling correction too
pixima => pixma
Copy your model schema.xml and solrconfig into conf folder:
download the cofig files:
wget https://raw.githubusercontent.com/geolba/tethys-search/master/schema.xml
wget https://raw.githubusercontent.com/geolba/tethys-search/master/solrconfig.xml
move them into the conf directory:
sudo mv /home/user/schema.xml /var/solr/data/tethys_data/conf/
sudo mv /home/user/solrconfig.xml /var/solr/data/tethys_data/conf/
Grant folder permissions for solr user
sudo chown -R solr:solr /var/solr/data/tethys_data/
Create solr index (c = Collection name; d = folder name)
sudo su - solr -c "/opt/solr/bin/solr create -c tethys_data -d /var/solr/data/tethys_data/ -n /var/solr/data/tethys_data/conf/"
Output Will be:
Created new core 'tethys_data'
Manage Solr service
