Re: Not able to use the highlighting feature! Want to return snippets of text
text:abstracthl=truehl.fl=textf.text.hl.snippets=2f.text.hl.fragsize=200debugQuery=true Three things to check: 1-) See your text field declared as suitable for highlighting. http://wiki.apache.org/solr/FieldOptionsByUseCase 2-) Increase hl.maxAnalyzedChars=Integer.MAX 3-) Increase maxFieldLengthInteger.MAX/maxFieldLength For some reason (complex analysis etc) snippets cannot be always generated. For this cases consider using hl.alternateField and hl.maxAlternateFieldLength
Re: Not able to use the highlighting feature! Want to return snippets of text
Take a look at the /browse request handler in the example solrconfig.xml and compare how it does highlighting to what you are doing. There are a lot of little details, so maybe even one might be missing. Also, you can only highlight stored fields, so make sure that text is stored. In the Solr example it is not stored and not intended to be stored, and highlighting should be performed using some other field containing the text as a stored field. -- Jack Krupansky -Original Message- From: 12rad Sent: Sunday, May 20, 2012 11:26 PM To: solr-user@lucene.apache.org Subject: Re: Not able to use the highlighting feature!

Re: Not able to use the highlighting feature! Want to return snippets of text
Hi,
I believe, in your colored fragmentsBuilder definition, you have not
mentioned anything in your pre and post tags and that may be the reason
that you are getting snippets of text, without highlighting.
Please refer http://wiki.apache.org/solr/HighlightingParameters and check
the hl.fragmentsBuilder section.
Try specifying the pre and post tags with information as mentioned below.
(same as wiki link above)

Not able to use the highlighting feature! Want to return snippets of text
I indexed a structured pdf document in Solr. The problem is when I search for a simple string - I get the entire content field as the response! I don't know how to change that. My requirement is that, lets say I search for metadata it should give me *Metadata*Discussion . . . 4 matches ... make sure that Tika users have a chance to get to all of the* metadata* created and/or extracted by Tika. == Original Problem == The original inspiration for this page was a Tika ... 10.7k - rev: 2 (current) last modified: 2010-08-02 18:09:45 But it gives me the whole document!- the entire string that was indexed. It seems like Lucene can only tell me in which field it occurred, not where in the field it occurred I posted the document like this curl http://localhost:8983/solr/update/extract?stream.file=/home/Desktop/DOCUMENTS/T.pdfstream.contentType=application/pdfliteral.id=DOC_Ncommit=truecaptureAttr=true; A query of *:* gives me the entire content of the document indexed in the text field And any search also returns the same thing.
