multiple sites use one apache solr server I am a beginner of using Apache Solr. I made a mistake two weeks ago.
I link two of my sites to one Apache Solr server. One is dev site, another is live site. There are some different data between these two sites. But I forgot to set "read only" on dev site.

Right now, everything is messed up. The dev site data shows on live site. How can I fix this? I tried to fix, but still no luck.

My fix steps:


Download Apache Solr Multiple Search on my dev site.
Set Apache Solr Search index access as "Read only"
Reindex all queue on my live site
Wait two days
Check the live site, still messy


I really appreciate if anyone could help.
apachesolr_multisite allows you to tenant multiple Drupal sites in one Solr search core, allowing searching across sites, or on single sites, but it must be configured. Go to admin/config/search/apachesolr/settings, click "Edit" on the Solr search environment, and examine the settings at the bottom of the form:



These must be configured properly for your use case.
