Subject: Re: Problem searching Field.Keyword field

Javadocs for Field.Keyword says:

Constructs a Date-valued Field that is not tokenized and is indexed, and=
 stored in the index, for return with hits.

For most purposes dealing with Strings, use Field.Text, unless you have a=
 date, a GUID or some other string you don't want tokenized or processed in=
 any way. This basically means that Field.Keyword indexes the field as-is.

>=A0Hi, =A0I have read several articles and postings that indicate that

>=A0for me, until I change to Field.Text. =A0Parts of the index and
>=A0search code are included below - mostly lifted from articles,etc,

>=A0KnowledgeBase web application that contains a category field, which
>=A0I want to be searchable. Searching using a query string of
>=A0category:Doc* or
>=A0category:Documentation does not find a hit unless I change the code
>=A0to add the category to the index as a Field.Text instead of
>=A0Field.Keyword. The field value is out there: =A0 I have verified this
