Then in the Regex Entity configuration tab that appears, fill in as explained below :
...
Source Metadatafield: the source from where the regular expression should be extracted. It can be set to “content”, “url”, or any ManifoldCF document field provided by the Repository Connector.
Associated regular expression: the regular expression used to extract data and fill the metadata. An example is given to retrieve the line in the document containing the word “option“, case insensitive.
Destination Metadatafield: the metadata (present in the Datafari Solr) to be filled. Some valid metadata are given as example. We do not recommend using these examples, as chances are high that it may collide with another indexing pipeline that may overwrite its value. You could for instance create dedicated fields for your metadata dedicated to regex, for instance regex_phones.
Value if truematch: if one match or more are found during the extraction and if this optional field is set, then this value will be set in the destination metadata, instead of the raw matches values.
Value if falseno match: if no match is found during the extraction and if this optional field is set, then this value will be set in the destination metadata.
