Alex D created SOLR-9356:
----------------------------
Summary: Highlight component added using Config API is not
functional
Key: SOLR-9356
URL: https://issues.apache.org/jira/browse/SOLR-9356
Project: Solr
Issue Type: Sub-task
Components: highlighter
Affects Versions: 6.0.1
Environment: SolrCloud on Windows with ZooKeeper 3.4.8
Reporter: Alex D
The configuration of a highlight component is not used when the component is
added using the Config API. I used the following steps to reproduce the issue:
1) Add the highlight component on a request handler:
<str name="hl">on</str>
<str name="hl.fl">Email</str>
<str name="f.name.hl.fragsize">0</str>
2) Execute a search using the request handler. I can see the default
configuration of the component returned in the results:
"highlighting":{"a":{"Email":["<em>roger2</em>"]},"b":{
"Email":"<em>roger</em>"]}
3) Add the highlight component using the Config API (see JSON below) & reload
collection. No errors were returned by Solr when adding the component.
4) Execute the same search as step2 and we can see the format of the highlight
is still using "em" instead of the new format from the Config API.
Content of the post to the Config API:
(Curl in a Windows' command prompt has some issues parsing the JSON so I used
Fiddler to send it to Solr)
