Highlighting priority
Hi, We are currently using Solr 4.3 and have highlighting activated on three different fields using FVH. Is it possible with Solr to prioritize highlighting for these fields ? I mean, how to configure Solr, when it's possible highlight the keywords from the first field, and highlight the rest of the keywords on the second field and so on. Is there any "Way Of Solr" for doing this ? Thank you and Best Regards Erwin

Solr Highlighting Best Practices Guideline
Hi, After having done the official Solr-Tutorial (https://lucene.apache.org/solr/4_5_1/) and read the Solr-Reference-Guide (https://www.apache.org/dyn/closer.cgi/lucene/solr/ref-guide/), I would like to ask whether someone can point me to best practices and/or tutorial on how to setup the highlighting function in Solr the right way ? I have googled but cannot find any relevant results. Could someone share her/his experience in using standard highlighther, fast vector highlighter and posting highlighter ? Thanks for every hints.

Hi Furkan, thanks for the reply. I was trying to get some guidelines on how to apply highlighter types correctly and maybe some comparison results between the three highlighter types (standard highlighter, fast vector highlighter and posting highlighter) Best Regards Erwin -Original Message- From: Furkan KAMACI [mailto:furkankam...@gmail.com] Sent: Tuesday, October 29, 2013 12:56 PM To: solr-user@lucene.apache.org Subject: Re: Solr Highlighting Best Practices Guideline This is a too broad question.

Performance problem on Solr query on stemmed values
Hi, I would like to know whether anyone have experienced this kind of phenomena. We are having performance problem regarding query on stemmed value. I've documented the symptoms which I'm currently facing: Search on field content Search on field spell Highlighting (on content field) Processing speed active active Active Slow active not active Active Fast active active not active Fast not active active Active Slow not active active not active Fast *Fast means 1000x faster than "slow". Field Content is our index field, which holds original text, and spell is the field with stemmed value. According to my measurement result, search on both fields (stemmed and not stemmed) is really fast. But when I start to take highlighting into our query it takes too long to process. Best Regards Erwin
RE: Performance problem on Solr query on stemmed values
Hi Erick, thank you for the reply. Yes, I'm using the fast vector highlighter (Solr 4.3). Every request should only deliver 10 results. Here is my schema configuration on both field: Field content contains in average around 5000 - 6000 words (only rough estimation).

This will be significantly slower than the search, especially if you have a large number of rows you're returning. You can get better performance in highlighting by using FastVectorHighlighter. See: https://cwiki.apache.org/confluence/display/solr/FastVector+Highlighter 1000x is unusual, though, unless your fields are very large or you're returning a lot of documents.
