[jira] [Commented] (SOLR-5127) Allow multiple wildcards in hl.fl
[ https://issues.apache.org/jira/browse/SOLR-5127?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14222931#comment-14222931 ]
Simon Endele commented on SOLR-5127:
------------------------------------
I implemented a similar solution, which seems to work for us.
May be interesting:
Using the PostingsSolrHighlighter an expression like {{hl.fl=*_text,myfield}} even causes the following exception:
{code}
java.lang.IllegalArgumentException: fieldsIn must not be empty
at org.apache.lucene.search.postingshighlight.PostingsHighlighter.highlightFieldsAsObjects(PostingsHighlighter.java:342)
at org.apache.lucene.search.postingshighlight.PostingsHighlighter.highlightFields(PostingsHighlighter.java:303)

> Allow multiple wildcards in hl.fl
> ---------------------------------
>
> Key: SOLR-5127
> URL: https://issues.apache.org/jira/browse/SOLR-5127
> Project: Solr
> Issue Type: New Feature
> Components: highlighter
> Affects Versions: 3.6.1, 4.4
> Reporter: Sven-S. Porst
> Attachments: highlight-wildcards.patch
>
>
> When a wildcard is present in the hl.fl field, the field is not split up at commas/spaces into components. As a consequence settings like hl.fl=*_highlight,*_data do not work.
> Splitting the string first and evaluating wildcards on each component afterwards would be more powerful and consistent with the documentation.
