# SearchFields

A comma-separated list of fields to search for entities, for example `DRECONTENT` or `DRETITLE`.

You must search at least one field, otherwise Named Entity Recognition does not return any results.

This parameter supports the `*` wildcard and regular expressions, with the following rules:

- A leading `*/` or a leading `/` is ignored. This is interpreted as the root of the document so has no effect.
- A `/` immediately followed by a `*` is interpreted as a field separator followed by a wildcard and is equivalent to the regular expression `/[^/]+`
- Any other use of `*` is interpreted as the regular expression quantifier (zero or more instances of something).

Example | Fields searched
--- | ---
`XXX/YYY` | The sub-field `YYY`, of the top level document field `XXX`.
`/XXX/YYY`
`*/XXX/YYY`
`*/XXX/*` | All direct sub-fields of the top level document field `XXX`.
`*/*/*` | All direct sub-fields of all top level document fields.
`*/A*/B*` | Fields named "B", "BB", "BBB" and so on, that are direct subfields of top-level fields named "A", "AA", "AAA" and so on. A field matching the path `AAA/BCD` would not be searched.
`*/A.*/B.*` | Fields whose name begins with a "B", that are direct subfields of top-level fields whose name begins with an "A".

Type: | String

Required: | No
Configuration Section: | Any section that you have defined for Named Entity Recognition settings
