DocBook XML is superficially compatible with DocBook SGML but has a slightly stricter DTD that we have been violating in a few cases. Although XSLT doesn't care whether the document is valid, the style sheets don't necessarily process invalid documents correctly, so we need to work toward fixing this. This first commit moves the indexterms in refentry elements to an allowed position. It has no impact on the output.

<para>
|
|
<command>CREATE TEXT SEARCH CONFIGURATION</command> creates a new text
|
|
search configuration. A text search configuration specifies a text
|
|
search parser that can divide a string into tokens, plus dictionaries
|
|
that can be used to determine which tokens are of interest for searching.
|
|
</para>
|
|
|
|
<para>
|
|
If only the parser is specified, then the new text search configuration
|
|
initially has no mappings from token types to dictionaries, and therefore
|
|
will ignore all words. Subsequent <command>ALTER TEXT SEARCH
|
|
CONFIGURATION</command> commands must be used to create mappings to
|
|
make the configuration useful. Alternatively, an existing text search
|
|
configuration can be copied.
|
|
</para>
|
|
|
|
<para>
|
|
If a schema name is given then the text search configuration is created in
|
|
the specified schema. Otherwise it is created in the current schema.

|
</para>

<para>

The user who defines a text search configuration becomes its owner.
