[Exist-open] is it possible to ignore elements from range index?

[ron.vandenbranden <ron...@ka...>]

Hi,


I have a question about the configuration of the current range index 
(eXist-2.1). Is it possible to exclude nodes from a range index using 
<ignore/>, or is this specific to the Lucene index? I thought I had used 
in range index definitions in the past, but may be misremembering. Given 
following test collection configuration:

   <collection xmlns="http://exist-db.org/collection-config/1.0">
     <index xmlns:tei="http://www.tei-c.org/ns/1.0">
       <fulltext default="none" attributes="no" alphanum="false"/>
       <lucene>
         <analyzer class="org.apache.lucene.analysis.standard.StandardAnalyzer">
           <param name="stopwords" type="java.util.Set"/>
         </analyzer>
         <analyzer id="ws" class="org.apache.lucene.analysis.WhitespaceAnalyzer"/>
         <text qname="p">
           <ignore qname="ignore"/>
         </text>
         <text qname="ignore"/>
       </lucene>
       <create qname="p" type="xs:string">
         <ignore qname="ignore"/>
       </create>
       <create qname="prefix" type="xs:string"/>
     </index>
   </collection>

...and a test collection with following document in /db/test/test.xml:

   <p><ignore>ignore me</ignore>this is paragraph text</p>

When this xquery is executed:

   let $coll := collection('/db/test')
   let $lucene := $coll//p[ft:query(., <query><regex>^this</regex></query>)]
   let $range := $coll//p[matches(., '^this')]
   return ($lucene, $range)

...only 1 paragraph element is returned, namely the one selected in the 
$lucene variable. The expression in the $range variable doesn't select 
anything. This suggests that <ignore/> does not apply to the range 
index, but I wanted to confirm this (it is not explicitly stated in the 
documentation for the range index). Also, I found no indexing errors in 
the logs.

Additionally, if <ignore/> is restricted to Lucene, does this mean that 
it will be possible to ignore elements from the new range index 
(eXist-develop branch)? I really hope to find some testing time soon...

Best,

Ron
