I have a class whose field "title" needs to be pre-tokenized by an
underscore instead of space. For example: "title": "Foo_of_Bar_FooBar" into
["Foo", "of", "Bar", "FooBar"]
I used the following to create a full-text index.
CREATE INDEX CLASS.title_lucene ON CLASS(title)
FULLTEXT ENGINE LUCENE METADATA {
"analyzer":
"org.apache.lucene.analysis.pattern.PatternReplaceCharFilter",
"analyzer_pattern": "_",
"analyzer_replacement": " ",
"index":
"org.apache.lucene.analysis.standard.StandardAnalyzer"
}
I tried using "pattern" and "replacement" instead of "analyzer_pattern" and
"analyzer_replacement". None of them worked.
*How do I pass the arguments to the constructor of the class specified?*
The aforementioned class is located here
<https://github.com/apache/lucene-solr/blob/master/lucene/analysis/common/src/java/org/apache/lucene/analysis/pattern/PatternReplaceCharFilter.java#L55>
.
