Please refer to chapter 12 of the Template Guide: http://www.jahia.org/jahia/webdav/site/jahia_org/shared/documentation/template/Draft_Jahia_Template_Developer_Guide_v0.3.pdf
or the Lucene syntax:http://lucene.apache.org/java/docs/queryparsersyntax.html
All the Jahia fields are independently indexed and several other properties (mode, language,...). So you can make easily make some complex requests on top of Lucene...
Finally, you may use any other web crawler on top of Jahia (e.g. Nutch). But this will not index hidden Jahia metadata, confidential pages, pages in various stages, etc.. Lucene was deeply integrated in order to automatically index all the Jahia content objects whatever their states, permissions, etc are. So you may try to replace it (with what?) but this will be a bit more complex (but the source code is of course available if you want to take a look).
Cheers,

Hi
I am implementing a site and Iwould like to know if it�s possible to use a multi criteria search (chose the type of document, chose a date �), I think it�s not possible but I would like to be sure. Thus my second question is it possible to use an others search engine with jahia.
Best regards
Geoffroy
