Re: FilterQueries with NRT
You can experiment with the backdoor NRT filters:
- replace COLOR:Red to {!parent which='COLOR:Red' v=''}
- add *NoOpRegenerator **into perSegFilter*
*- **monitor cache stats. *

Apache SOLR Design Query
Hi team, We have a business case like the below one. There are nearly 150 GB of docs(pdf/ppt/word/xl/msg) files which are in stored in a N/w Path as of now. To implement text search on these , we are planning to use solr search in these. Listed below is the plan. 1)Using a high configuration Windows server(16 GB RAM , 1 TB Disk etc) 2)Keep all the files in this server. 3)Index all the above docs to solr server(Solr installed in the same windows server). Will use solr post command to post documents to this server. 4)Using a Web application user can further add or remove files to/from shared path in this server. 5)Web UI to search the text from these docs. and display the file Names. User can click and download the files Listed are the queries what we have. 1)Since we cannot index fields here, (as search is across all text in the docs of various types. User can search for any text and it might be in XL or in DOC or in PPT or in .MSG files), whether querying(Rest API from the Web ) the search data will have any performance hit? 2)Is it a right decision to keep the physical files in the Shared folder of Server itself(as a shared drive) instead of storing it in a DB or any other storage? Regards, MS
Solr 6.6.3 won't start - unrecognized vm option "UseParNewGC" - Java 10.0.1
Running into an issue beyond my experience level. In Installed and started Solr 7.3. But, then I realized I need to use an older 6.x version (for Drupal) So, I installed Solr 6.6.3. But, it will not start. The message I get is: **Still not seeing Solr listening on 8983 after 180 seconds!* *tail: /Applications/solr-6.6.3/server/logs/solr.log: No such file or directory** I get the same same result, whether I use *bin/solr start* or *sudo*. The solr.log is definitely missing. But there is a Solr-8983-console.log. This shows the message below: **Java HotSpot(TM) 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.* *Unrecognized VM option 'UseParNewGC'* *Error: Could not create the Java Virtual Machine.* *Error: A fatal exception has occurred. Program will exit.** Java -version displays as 10.0.1. This is a work computer with security needs, and I believe I need to keep it as updated as possible: **java version "10.0.1" 2018-04-17* *Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10)* *Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.1+10, mixed mode)** Also tried with Solr 6.6.3, 6.6.0 and 5.0.0 with same failure and log message. If relevant, I'm on a 2015 macbook pro, using high sierra 10.13.3
Re: Solr 6.6.3 won't start - unrecognized vm option "UseParNewGC" - Java 10.0.1
Just what it says, you are using (or rather the start scripts that Solr 6.6.3 uses) are using options not supported in Java 10. Java 10 is in process of being verified to work with Solr, see this JIRA in the 7.3.1 release notes: SOLR-12141: Fix "bin/solr" shell scripts (Windows/Linux/Mac) to correctly detect major Java version and use numerical version comparison to enforce minimum requirements. Also remove obsolete "UseParNewGC" option. This allows to start Solr with Java 10 or later. (Uwe Schindler) I'd pretty strongly recommend moving back to the version of Java specified with 6.6.3, probably Java 9. Java 8 has the most mileage with that Solr code base.

Re: Solr 6.6.3 won't start - unrecognized vm option "UseParNewGC" - Java 10.0.1
Erick, Thank you, and sorry for 'beginner' questions! So, I've installed a second version of Java. I believe 8? (Titled: oracle65-1.8.0.172), and I turned it on for the local Solr-6.6.3 folder. Double checked it's using that version (using homebrew, cask and jenv) But... I'm getting exactly the same error still. no such file, and the console.log Java HotSpot(TM) 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release. Unrecognized VM option 'UseParNewGC' Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. thoughts?

Re: Solr 6.6.3 won't start - unrecognized vm option "UseParNewGC" - Java 10.0.1
You may need to set JAVA_HOME or PATH variables to point to your java 8 . Possibly both.
