There's somewhat confusing information in Jira on this. One issue seems to deprecate shareSchema in 4.4. Deprecation in one major release implies that the feature will be completely removed in the next major release, but should still work until then: https://issues.apache.org/jira/browse/SOLR-4779 Another issue talks about fixing str/bool/int detection on parameters like shareSchema in 4.10 and 5.x (trunk at the time): https://issues.apache.org/jira/browse/SOLR-5746 You said you're still running 4.x, specifically 4.10.4, which means that I would expect shareSchema to still work. Although this is technically a bug, I don't think it's a big enough problem to warrant fixing in the 4.10 branch. The first thing I would advise trying is to change the parameter from str to bool. Hopefully that will fix it. There may have been a misstep in the patch for SOLR-5746. Do you actually NEED this functionality? It is no longer there in 5.x, so it may be a good idea to prepare for it's removal now. The amount of memory required for an IndexSchema object for each core should not be prohibitively large, unless you've got thousands of cores ... but in that case, you're already dealing with fairly significant scaling challenges, this one may not matter much. If you do need the functionality, then a jira is in order to work on it. I can't guarantee that there will be a 4.10.5 release, even if a fix is committed to the 4.10 branch. I have not examined the code to see what's actually happening. Your response will determine whether I take a look. Thanks, Shawn
