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 DICTIONARY</command> creates a new text search
|
|
dictionary. A text search dictionary specifies a way of recognizing
|
|
interesting or uninteresting words for searching. A dictionary depends
|
|
on a text search template, which specifies the functions that actually
|
|
perform the work. Typically the dictionary provides some options that
|
|
control the detailed behavior of the template's functions.

If a schema name is given then the text search dictionary is created in the
|
|
specified schema. Otherwise it is created in the current schema.
