[jira] [Updated] (SOLR-8212) Standard Highlighter Inconsistent with
NGram Tokenizer
[ https://issues.apache.org/jira/browse/SOLR-8212?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Esther Quansah updated SOLR-8212:
---------------------------------
Description:
Noticing some inconsistent behavior with the Standard Highlighter and its function on terms that use the NGram Tokenizer. Ex:
I created a field called "title_contains" which uses the NGram Tokenizer and I indexed the term "bronchoscopy". Querying "co" on the title_contains field should return "bronchos<em>co</em>py", but the Standard highlighter returns "bronchoscopy" without the highlighting information.
I created a test called testNgram() which tests the above example using (1) the Standard Highlighter on the ngram field type and (2) the Fast Vector Highlighter on the ngram field type. The first fails and the second passes.
Problem identified:
