Hi, trying to use the Luke tool supplied with Lucene to investigate search issues on an umbraco site but can't get it running. I get the following error when running Luke.cmd (Windows 11)- "Could not create the Java virtual machine. A fatal exception has occurred. Program will exit." Has anybody else encountered this before? I've increased the JS heap size to 1 gig which is the most common suggestion for this error, but it's still occurring.

JRE from https://www.java.com/en/download/ and then Luke 4.8 from https://github.com/DmitryKey/luke/releases/tag/4.8.0 and launching the .jar file. Still works for me (umb 13 indexes) https://cdn.discordapp.com/attachments/1326532588722196550/1326861396498972692/image.png?ex=6780f778&is=677fa5f8&hm=05cb3204962c5ce5b53905072e0edd6afd8f9029ade89288731860579e3534f5&

Thanks @Mike Chambers I was able to get it working with this version - I was also having trouble getting the latest version of Java installed which also resolved the issue with Luke v9/10, however these are incompatible with the indexes Umbraco generates

Suporised actually to see that luke 4.8 reports that Umb 13 indexes have a lucene format of 4.2! 🤨

Why don't you use the backoffice of Umbraco to check the indexes, that works pretty well in most cases 🙂

for the same reason I use any WYSIWYG UI 🙂 the query builder (no need for lucene query knowledge) and actually seeing what's in the index not just a result set etc....
