Segments in solr index gets deleted after every restart

I have an issue with respect to increasing space on my Solr servers. Whenever I see that the allocated space is almost full for a particular server, I perform a service solr restart and this clears up some space and things work normally from there for some time. Again this builds up and I get a

Re: Return parent's records which has more than certain number of childs

If you are indexing the parent/child as a block, then you know number of children when you are indexing parent and can store that as a field. That would be most efficient. The best place to calculate that information is probably a custom Update Request Processor. Regards, Alex.

Return parent's records which has more than certain number of childs

Hi, Would like to check, in the parent/child nested document, is it possible to return only records with a certain number of child? For example, I want to return all the parent's records which has more than 100 child. Is it possible to be done? I'm using Solr 6.1.0 Regards, Edwin

Re: Default stop word list

Do not remove stop words. Want to search for “vitamin a”? That won’t work. Stop word removal is a hack left over from when we were running search engines in 64 kbytes of memory. Yes, common words are less important for search, but removing them is a brute force approach with severe side

Re: Default stop word list

Thanks Shawn. This is the best answer I have seen, much appreciated. A follow up question, I want to remove stop words from the list, but if I do, then search quality will degradation (and index size will grow (less of an issue)). For example, if I remove "a", then if someone search for "For a

Re: Solr embedded jetty jstack

Responding to my own query. I got this fixed. The solr startup was maintained by systemd script which was configured with "PrivateTmp=true". I have changed that to "PrivateTmp=false" and "/tmp/hsperfdata_/" is not removed after server startup then jstack worked. On 8/29/16 11:31 AM,

Re: How to update from Solr Cloud 5.4.1 to 5.5.1

Shawn, Do you (or anybody else here) know of the upgrade steps from 6.1 to 6.2 in this case? The release notes of 6.2 do not mention anything about upgrading, but 6.2 has some good bugfixes. If 6.2 made changes to the index format, is a drop-in replacement from 6.1 to 6.2 still possible?

Unicode collation - Sorting text for multiple languages

Hi, I was looking at Unicode Collation @ Wiki ( http://wiki.apache.org/solr/UnicodeCollation#Sorting_text_for_multiple_languages ) and it seems to suggest that: Use the Unicode "default" collator (to overcome/minimize increase in disk and indexing costs) over defining collated fields for each

Atomic Update w/ Date Copy Field

We recently started using atomic updates in our application and have since noticed that date fields copied to a text field have varying results between full and partial updates. When the document is fully updated the copied text date appears as expected (i.e. -MM-dd'T'HH:mm:ss.SSSZ); however,
