<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>
