Doxygen Deep Search

What it is

The default Doxygen search engine only search for page titles and referenced code names, and it can't match partial names.
The other Doxygen search engines only work server-side.
Doxygen Deep Search is a replacement for the default search engine, it works both online and offline and search the whole text for occurences, even partial.

Install

Generate your Doxygen project with the following HTML options enabled:
SEARCHENGINE
SERVER_BASED_SEARCH
EXTERNAL_SEARCH

This will generate a searchdata.xml file.
Append <script id="searchdata" type="text/xmldata"> to the content of html/search.html, then paste the content of searchdata.xml, and end with </script>.
Replace html/search/search.js by Doxygen Deep Search search.js.

That's it !

If you need to automate this in a script:

BATCH

copy /y search.js html/search/search.js  
echo ^<script id="searchdata" type="text/xmldata"^> >> html/search.html  
type searchdata.xml >> html/search.html  
echo ^</script^> >> html/search.html

BASH

cp search.js html/search/search.js  
echo "<script id=\"searchdata\" type=\"text/xmldata\">" >> html/search.html  
cat searchdata.xml >> html/search.html  
echo "</script>" >> html/search.html
