Since some preparation work had already been done, the only source changes left were changing empty-element tags like <xref linkend="foo"> to <xref linkend="foo"/>, and changing the DOCTYPE. The source files are still named *.sgml, but they are actually XML files now. Renaming could be considered later. In the build system, the intermediate step to convert from SGML to XML is removed. Everything is build straight from the source files again. The OpenSP (or the old SP) package is no longer needed. The documentation toolchain instructions are updated and are much simpler now.

|
<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.

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

The <literal>PARSER</literal> and <literal>COPY</literal> options are mutually

parser selection is copied too.
