Erick Erickson commented on SOLR-10561:
---------------------------------------
First, unless it's best to discuss topic on the user's list first, we try to
reserve the JIRA system for known code issues rather than usage questions.
Velocity is a _demonstration_ UI, I'd guess there's an arbitrary limit in
there, you can look through the velocity code and see. But you simply cannot
expose velocity to end users, that gives them total access to your corpus you
give them your Solr URL, and you'd give users essentially unlimited access.
Try using the raw URL, plus insure that your highlighter configuration in
solrconfig.xml doesn't have an invariant for the max number of snippets allowed.
You can find instructions for the Solr user's list here:
http://lucene.apache.org/solr/community.html
I'll close this JIRA, we can open a new one if there's a code change required.
Best,
Erick

> Key: SOLR-10561
> URL: https://issues.apache.org/jira/browse/SOLR-10561
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: contrib - Velocity
> Affects Versions: 6.5
> Environment: Windows 10
> Reporter: Sam
>
> Hi, I've been working on a Solr project in Windows for a while... here i'm
> trying to index a book containing (118,704 words) and then do a basic term
> search, however the Velocity interface is not returning the expected results,
> Velocity will only return a maximum of 13 terms highlighted within 13
> snippets, even though my snippets is set to much higher than 13. I've tried
> this both with the Original and Unified highlighter with the same results.
> The XML data file for my book has the following fields as shown below:
> <?xml version="1.0" encoding="UTF-8"?>
> <add>
> <doc>
> <field name="id">WALDEN-utf8.xml</field>
> <field name="title">WALDEN</field>
> <field name="catagory">Sam-tests</field>
> <field name="content">
> (118,704 words) ... too large to paste here!
> </field>
> <field name="keywords"></field>
> </doc>
> </add>
> - I've modified my schema via the API and indexed my file successfully.
> - I've also managed to turn on highlighting using the following command:
> curl http://localhost:8983/solr/mycore/config/params -H
> 'Content-type:application/json' -d
> "{"set":{"browse":{"hl":"on","hl.method":'original',"hl.snippets":'1000',"hl.fl":'*'}}}"
> Again Velocity will return the correct number of highlighted terms, in the
> correct number of snippets if i reduce the hl.snippets field to anything less
> than or equal to 13.
> - I've also read the documentation online at:
> https://cwiki.apache.org/confluence/display/solr/Highlighting
> and it clearly says:
> "hl.snippets 1 Specifies maximum number of highlighted snippets to
> generate per field. It is possible for any number of snippets from zero to
> this value to be generated."
> I'm not sure why this is happening, is my approach to the whole project
> wrong? I have read that Solr can successfully index many books. The Admin UI
> logs doesn't show any problems either, also I've been looking on the net but
> still no luck as to as why this is happening. Please help and apologies if my
> method or place of escalation is not correct (newbie :)).
> Please let me know if you require further information as well.
