[jira] [Created] (SOLR-3792) NPE in highlighter under certain
conditions
Yoni Amir created SOLR-3792:
-------------------------------
Summary: NPE in highlighter under certain conditions
Key: SOLR-3792
URL: https://issues.apache.org/jira/browse/SOLR-3792
Project: Solr
Issue Type: Bug
Components: highlighter
Affects Versions: 4.0-BETA
Environment: Windows 7, Java 6 or 7
Reporter: Yoni Amir
Under certain conditions, there is an exception in highlighter component. The stacktrace is shown below.
The conditions are:
1) Add a document with a field that has empty value. E.g., with solrj api:
document.addField ("field1", "");
(Maybe this is not a valid value or use-case, but Solr stills allows it!!)
2) have solr.WhitespaceTokenizerFactory as the tokenizer of the analyzer chain for that field.
3) make sure that this field should be highlighted. In my case, I was using hl.requireFieldMatch=false, and actually I was searching on another field.
4) Using edismax, search for a phrase, e.g., "foo bar" (including the quotation marks)
5) The document mentioned before should be part of the search results.
6) This exception occurs:
