<!--
    The configuration element configures the indexing behaviour of the lucene
    backed query handler . It allows you to define indexing
    aggregates and configure which properties of a node are indexed.
    This element must contain all the namespace declarations that are used
    throughout this configuration.
-->
<!ELEMENT configuration (aggregate*,index-rule*)>

<!--
    Each aggregate element defines an indexing aggregate based on the name of a
    primary node type.
-->
<!ELEMENT aggregate (include*)>
<!ATTLIST aggregate primaryType CDATA #REQUIRED>

<!--
    An include element contains a relative path pattern using either an exact
    node name or *. Nodes that match the path pattern against the root of an
    indexing aggregate are included in the aggregated node index. An include
    element may optionally specify a primary node type name that needs to match
    for the included node.
-->
<!ELEMENT include (#PCDATA)>
<!ATTLIST include primaryType CDATA #IMPLIED>

<!--
    An index-rule element defines which properties of a node should be indexed.
    When a node is indexed the list of index-rules is check for a matching
    node type and whether the condition is true. If a match is found the
    property is looked up.
    The index-rule element also contains a boost value for the entire node
    being indexed. A value higher than 1.0 will boost the score value for a node
    that matched this index-rule.
-->
<!ELEMENT index-rule (property*)>
<!ATTLIST index-rule nodeType CDATA #REQUIRED
                     condition CDATA #IMPLIED
                     boost CDATA "1.0">

<!--
    A property element defines the boost value for a matching property and a
    flag that indicates whether the value of a string property should also be
    included in the node scope fulltext index. Both boost and nodeScopeIndex
    attributes only affect string properties and are ignored if the property
    is not of type string.
-->
<!ELEMENT property (#PCDATA)>
<!ATTLIST property boost CDATA "1.0"
                   nodeScopeIndex CDATA "true">

<!--
    An analyzer element with property elements in it defines which analyzer is to 
    be used for indexing and parsing the full text of this property. If the analyzer
    class can not be found, the default analyzer is used. The node scope is always 
    indexed with the default analyzer, so might return different results for search 
    queries in some rare cases.
