<div class="toc"><dl class="toc"><dt><span class="section"><a href="ch03s02s01.html">New Stemmers</a></span></dt></dl></div><p class="summary">Overview design of Search mechanism.</p><p>The serching is a fully client-side implementation of querying texts for content
searching. There's no server involved. So, the search queries by the users are processed by
JavaScript inside the browser, and displays the matching results by comparing the query with
a simplified 'index' that too resides in JavaScript. Mainly the search mechanism has two
parts. </p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>Indexing: First we need to traverse the content in
the docs folder and index the words in it. This is done
by <code class="filename">webhelpindexer.jar</code> in
<code class="filename">xsl/extentions/</code> folder. You can
invoke it by <code class="code">ant index</code> command from the
root of webhelp of directory. The source of
webhelpindexer is now moved to it's own location at
<code class="filename">trunk/xsl-webhelpindexer/</code>.
Checkout the Docbook trunk svn directory to get this
source. Then, do your changes and recompile it by simply
running <code class="code">ant</code> command. My assumption is that
it can be opened by Netbeans IDE by one click. Or if you
are using IntelliJ Idea, you can simply create a new
project from existing sources. Indexer has extensive
support for features such as word scoring, stemming of
words, and support for languages English, German,
French. For CJK (Chinese, Japanese, Korean) languages,
it uses bi-gram tokenizing to break up the words (since
CJK languages does not have spaces between
words).</p><p> When <code class="code">ant index</code> is run, it generates five output files: </p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: circle; "><li class="listitem"><p><code class="filename">htmlFileList.js</code> - This contains an array named
<code class="code">fl</code> which stores details all the files indexed by the indexer.
Further, the doStem in it defines whether stemming should be used. It defaults
to false.</p></li><li class="listitem"><p><code class="filename">htmlFileInfoList.js</code> -
This includes some meta data about the indexed
files in an array named <code class="code">fil</code>. It
includes details about file name, file (html)
title, a summary of the content. Format would look
like, <code class="code">fil["4"]= "ch03.html@@@Developer
Docs@@@This chapter provides an overview of how
webhelp is implemented.";</code>
</p></li><li class="listitem"><p><code class="filename">index-*.js</code> (Three index files) - These three files
actually stores the index of the content. Index is added to an array named
<code class="code">w</code>.</p></li></ul></div></li><li class="listitem"><p> Querying: Query processing happens totally in client side. Following JavaScript
files handles them. </p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: circle; "><li class="listitem"><p><code class="filename">nwSearchFnt.js</code> - This handles the user query and
returns the search results. It does query word tokenizing, drop unnecessary
punctuations and common words, do stemming if docbook language supports it,
etc.</p></li><li class="listitem"><p><code class="filename">{$indexer-language-code}_stemmer.js</code> - This includes the
stemming library. <code class="filename">nwSearchFnt.js</code> file calls
<code class="code">stemmer</code> method in this file for stemming. ex: <code class="code">var stem =
stemmer(foobar);</code>

Upgrade ANT doc build infrastructure to assemble PDFs: - remove non-namespaced DocBook source and add namespaced DocBook source. - add Apache FOP 1.1 - copy fonts, images, XSL into _build, establishing new asset structure. The original structure remains until all guides using it can be upgraded, and several other issues can be resolved. - updated build.xml to allow for per-target build properties. - upgraded the P4SAG to use the new infrastructure. - tweaked admonition presentation in PDFs to remove admonition graphics, and resemble closely the presentation used in the new HTML layout, including the same colors. With these changes, building PDFs involves using a shell, navigating into the guide's directory (just P4SAG for now), and executing "ant pdf". Issues still to be resolved: - PDF generation encounters several warnings about missing fonts (bold versions of Symbol and ZapfDingbats), and a couple of locations where the page content exceeds the defined content area. - Due to issues within Apache FOP, PDF generation emits a substantial amount of output that is not easily suppressed without losing important warning information. - Apache FOP's interface to ANT does not expose a way to set the font base directory. The current configuration does work under Mac OSX, but further testing on Windows will need to be done to determine if the relative paths defined continue to work. The workaround is for Windows users to customize the fop-config.xml to provide absolute system paths to the required fonts. - HTML generation needs further browser testing, and exhibits broken navigation on iOS browsers within the TOC sidebar. - A number of PDF and HTML presentation tweaks still need to be made, for example: sidebars, gui* DocBook tags, whitespace, section separation, etc. |
