Just had similar issue - works for some, not others. First thing to look at is hl.maxAnalyzedChars is the query. The default is quite small. Since many of my documents are large PDF files, I opted to use storeOffsetsWithPositions="true" termVectors="true" on the field I was searching on. This certainly did increase my index size but not too bad and certainly fast. https://cwiki.apache.org/confluence/display/solr/Highlighting
Beware of NOT plus OR in a search. That will certainly produce no highlights. (eg test -results when default op is OR) -----Original Message----- From: Ali Husain [mailto:alihus...@outlook.com] Sent: Thursday, 15 June 2017 11:11 a.m. To: solr-user@lucene.apache.org Subject: Issue with highlighter Hi, I think I've found a bug with the highlighter. I search for the word "something" and I get an empty highlighting response for all the documents that are returned shown below. The fields that I am searching over are text_en, the highlighter works for a lot of queries. I have no stopwords.txt list that could be messing this up either. "highlighting":{ "310":{}, "103":{}, "406":{}, "1189":{}, "54":{}, "292":{}, "309":{}}} Just changing the search term to "something like" I get back this: "highlighting":{ "310":{}, "309":{ "content":["1949 Convention, <em>like</em> those"]}, "103":{}, "406":{}, "1189":{}, "54":{}, "292":{}, "286":{ "content":["persons in these classes are treated <em>like</em> combatants, but in other respects"]}, "336":{ "content":[" be treated <em>like</em> engagement"]}}} So I know that I have it setup correctly, but I can't figure this out. I've searched through JIRA/Google and haven't been able to find a similar issue. Any ideas?
