Regex Extractor uses Regular Expression to extract the data. It simply applies the regex provided in the field on the document and takes the match of the regex as the extracted value.
Regex Extractor takes only the first match as the extracted value. But if Global option is given on the field, then the value of the field is set by taking all the matches but separated by comma.

Skill extractor applies the document model on the document. Then simply sets the value on the Field according to the Skill Field mapped in the definition.

Form Extractor works by finding all key-value pairs in the document. Then for each field the extractor tries to match the field with the keys in the document. A field is considered as match with a key if :
All Included keywords are matched
All Excluded keywords are not matched
To match a field with key Date but not Date of Birth include the keyword date and exclude the keyword birth.
Keys in the document are matched in the order they appears in the document. Once a key is matched with a field, the matching stops for the field. All other fields are ignored for the field. The extractor takes the value of the matched key, applies post processing and sets it as the value of field. No value is set if no key is matched.
