Regex to match one of two words

I have an input that can have only 2 values Published or Deprecated. What
regular expression can I use to ensure that either of the two words was
submitted?

I tried with different regular expressions (as in the [1], [2]) that
contains most generic syntax.. But Solar throws parser exception when
validating these expressions.. Could someone help me on writing this
regular expression that will evaluate by the Solar parser.

[1] /^(PUBLISHED)?(DEPRECATED)?$/
[2] /(PUBLISHED)?(DEPRECATED)?/


SolrCore org.apache.solr.common.SolrException:
org.apache.lucene.queryParser.ParseException: Cannot parse
'overview_status_s:/(PUBLISHED)?(DEPRECATED)?/': '*' or '?' not allowed as
first character in WildcardQuery
at
org.apache.solr.handler.component.QueryComponent.prepare(QueryComponent.java:108)

Dinusha.

Or a boolean field for published, with false meaning deprecated.

Why use regular expressions at all?

Try:

published OR deprecated
