[opencms-dev] search xmlcontent

[Claus Priisholm]

The first step is to make sure the Lucene index actually support the 
kind of query you want to make. I.e. the contents of the specific tags 
from your xmlcontent must be present in a separate Lucene index field. 
Per default OpenCms extracts all text from the contents and put into the 
contents field in the Lucene index, so you cannot limit the search to 
only look at specific parts of the xmlcontens.

In v. 6 this means creating a new class for handling the indexing of the 
specific types of xmlcontents (and set it in the opencms-search.xml).
In v. 7 you can map fields via the configuration, so you can most likely 
avoid the step of making a specific class for the indexing (unless you 
have explicit needs as far as controlling exactly how each field is 
analyzed, tokenized, indexed...)

Once the Lucene index holds the appropriate information then you must 
define your query such that it only looks at the appropriate fields 
(instead of the generic contents field).

This is mostly Lucene stuff, the OpenCms API hides some of the OpenCms 
specifics, but you'll need to have an idea of how Lucene works.
