Parser configuration for Db2 Text Search

You can configure some of the settings that are used for XML search.

Note: From 12.5 onwards Db2 includes OpenSearch and ElasticSearch engines for Indexing. The parser configuration setting explained here is only specific to ECMTS as text search server. It is not applicable to OpenSearch and ElasticSearch.

All parser configuration parameters are located in the parser_config.xml file, in the XML element defining the parser, com.ibm.es.nuvo.parser.xml.XMLParser. Each parameter is specified by a Parameter element of this form:
